There are a few absolutely normal things that people have said to me over the years that remind me of these people - relentlessly. These aren't mean things, or complimentary things. They aren't good or bad. But they are unforgettable.
Example 1 -- I comment to a couple friends that I cannot NOT observe and take note of the travel times on the electronic highway sign on my commute home. The best times I've seen are 9 and 17 minutes. Friend 1 is impressed. The best he's seen are 9 and 18. Friend 2 makes a joke about how we really "like to live it up, don't we!" I think of Friend 2
every single time I see this sign.
Example 2 -- A friend in college says to me, "Why didn't anyone tell me I'm supposed to shave my hair
with the grain!?" I think of her
every single time I shave my armpits.
So remember, folks, some little thing you say may just be that unforgettable thing to your completely neurotic friend for as long as they live (or drive and shave).
