I'm on the island with my wife. Her sister's laptop runs a lot slower than hers - even though her sister's laptop is newer.

I'm pretty good with computers so I start explaining possible causes why.

Me: The reason why your computer is faster is because it has 8gigs of ram and a solid state.

Wife: Oooo, 8 gigs.

In a half joking/half mocking tone. It's one of those subtle things where it's obvious that what I'm saying isn't being taken the way I want it to.

Me: Ok. No more advice then. You lost your opportunity.

She obviously wants to know more but she lost her opportunity. So now her sister's laptop is going to continue running slower while I bring her laptop back to the states. That means she's going to be stuck with her problem.

I'm not going to go and give advice about simple solutions when that advice isn't taken or appreciated in the manner I expect. Really simple stuff. Doing otherwise would be rewarding bad behavior.

I finished giving the advice 15 minutes later at lunch.
