An Engineer’s Guide to Relationships:

Wife vs. Girlfriend (A Totally Unscientific Systems Analysis)

By Mark Kendall — LearnTeachMaster.org

(68 years of uptime, zero intention of rebooting)

Engineers are simple creatures.

We like clarity.

We like systems that behave predictably.

We like knowing where the logs are.

Which raises a perfectly reasonable architectural question:

From a systems engineering perspective, is it better to have a wife… or a girlfriend?

Before anyone gets offended, relax.

This is satire.

And if you can’t laugh at systems thinking applied to human relationships, you probably shouldn’t be dating an engineer anyway.

The Engineer’s First Mistake: Treating Relationships Like Software

Let’s get this out of the way.

Engineers always try to model relationships like systems:

• Inputs

• Outputs

• SLAs

• Failure modes

• Change management

This is adorable.

And completely wrong.

But since we’re engineers… we’re going to do it anyway.

Option A: The Wife (Long-Term Production System)

Think of a wife as a mission-critical, long-running production system.

Pros

• Deep domain knowledge of you (sometimes frighteningly accurate)

• Handles edge cases you didn’t even know existed

• Knows your failure patterns before you trigger them

• Designed for durability, not demos

Cons

• Zero tolerance for undocumented breaking changes

• Remembers all prior incidents (even ones you thought were patched)

• You cannot “just refactor later”

• Downtime discussions are… intense

Engineer Translation:

Stable. Battle-tested. High availability.

But every change request goes through Change Advisory Board (CAB).

Option B: The Girlfriend (Innovative New Service)

A girlfriend is more like a greenfield microservice.

Pros

• Lightweight

• Exciting new features

• Faster iteration cycles

• More enthusiasm during initial deployment

Cons

• Requirements may be… evolving

• Documentation is sparse

• You are still discovering hidden dependencies

• Long-term scalability unclear

Engineer Translation:

Fun. Flexible. High innovation velocity.

But you’re still figuring out what happens under load.

The Truth Engineers Hate to Admit

Here’s the thing no architecture diagram will show you:

The problem isn’t wife vs. girlfriend.

The problem is the engineer.

Engineers:

• Over-optimize

• Under-communicate

• Assume silence means “everything is fine”

• Try to debug emotions instead of listening to them

We think clarity is kindness.

Sometimes it is.

Sometimes it’s just bluntness with better formatting.

Male vs. Female Perspectives (Playfully, I Promise)

Engineers (often male):

• “Just tell me the requirements.”

• “Why didn’t you say this sooner?”

• “Can we schedule this conversation?”

Partners (often female):

• “I did tell you.”

• “You didn’t hear me.”

• “No, this is not a meeting.”

Both sides are right.

Both sides are exhausted.

Neither side read the README.

So… Which Is Better?

Here’s the senior-engineer answer:

It depends on the lifecycle stage of the system.

If you’re still experimenting, learning who you are, and shipping MVPs of yourself:

• A girlfriend may make sense.

If you’ve moved into reliability, meaning, and long-term impact:

• A wife is a powerful co-architect.

But either way…

The Real Engineering Lesson

The best systems aren’t the ones with the fewest bugs.

They’re the ones where:

• People feel safe reporting issues

• Changes are discussed, not avoided

• The system evolves because both sides care

And that, my fellow engineers, has nothing to do with gender—

and everything to do with maturity.

Final Disclaimer

This article was written by a 68-year-old engineer who:

• Has seen enough production outages to value stability

• Still appreciates innovation

• And fully understands that relationships are not systems

But if they were?

You’d want one built on trust, humor, patience…

and someone who knows when to pull you away from the keyboard.
