What do I say in a secret love letter (middle school)?

Just tell them that you like them and that you want to go out with them and to have them meet you at a secret location to find out who wrote the letter but dont say anything that you wouldnt in person cause they could find out then you will be in trouble

Honey, don't do it, it'll end badly....trust me. Just come straight out with it and tell the person how you feel.
