I have the worst short-term memory ever. It usually involves forgetting to buy something at the grocery store… even if I have it written on a sheet of paper with me. I forgot good things and bad things, but I do remember the feelings. Earlier today, Nick said something cute. Later, he asked me if he was cute earlier.* I said yes, but I didn’t remember how.
I think it’s one of those things that will be explained in 400 years after extensive scientific research, like whether or not your baby will be left-handed.
