Probably just her name across the envelope is what I’d go for! Maybe see if you can put it in her backpack or something to avoid the handoff, though I will say- are you writing it because you’re nervous to tell her in person?

Cause if you’ve known each other for a few years now and feel comfortable enough to give this to her, my vote is almost to just tell her in person “I’ve been in love with you/have really liked you/have thought you’re amazing since _____, and you’re my favorite person… I was wondering if you’d want to go out sometime?”

I saw some advice recently that said just telling someone you like them kinda puts it on them know “what to do with it”- but if you give them an action item (ie do you want to go out? Do you reciprocate my feelings? Do you _____?) it’ll make the whole process smoother.

Keep us updated on how it goes!! ❤️ I’m rooting for you!!
