Tell him/her/it, "You are my sunshine, my only sunshine. You make me happy when skies are gray. You'll never know dear, just how much I love you. Please, don't take my sunshine away." (Say it with a straight face. It's funnier that way.)
What are some cute things to say to your crush?
IMO, cute is overrated. If I have a crush on someone, I want to spend some time getting to know them in order to know if it's all in my head or are they really that fabulous. So, I'm going to ask them what they like to spend their time doing and hopefully their answer isn't "texting my friends".
