How do you tell someone you like them?
Say "I like you" then pull up your shirt. If it'll work on me, it'll work on anybody.
Ugh. You are so gross. Seriously, this is important.
Alright, say that you feel really comfortable with them and then lean in to kiss them. If they go with it, then good for you. If not, just say that you were lost in the moment or something.
