It's sweet when someone remembers every tiny detail about you, not because you keep reminding them.. Because they pay attention.
I find it really thoughtful when someone says with excitement in their eyes and voice "Oh yeah, I remember. You've told me about it, haven't you? And what happened next?" I know it's just a simple response, but hey who happens not to like it, huh? Stayed up late just to accompany me with while I was pretty mad with shitty things around. You could've just gone to bed and ignored the mad me that time. That was a very kind of you.
Since paying attention isn't not that easy, you could've just walked away and said goodbye at the moment. I greatly appreciate everything. Yes, everything.
