Say all of that but then add “or whatever” to the end
How do you nonchalantly say "Hey you're cute and I get this horrible but absolutely amazing feeling in my stomach whenever I see you because I love you and want to cuddle with you and watch movies and go to prom with you"
Please let yourself be proud of small things. Please do that. Please allow yourself to get really excited about playing a video game well or sending an ask you were nervous about or letting a bug outside or peeling the whole orange in one try. Please get so excited about that. Please. That’s so cool I’m so glad you did it.
