I love Wilco so dearly, and this song makes me happy.

I left you behind I know its been along time, but I’m not over you
Don’t forget the flowers someday, I hope I do
You’re tryin’ my patience, try pink carnations, red roses and yellow
daffodils
Don’t forget the flowers someday
I know I will
Don’t forget the flowers someday, I know I will

Reading the lyrics I realized it’s actually kinda sad.
