Spring Break

This spring break I am planning on going to Texas to surprise my boyfriend. It's a long story but he got in a fight with his step dad and he is just staying with some family up in Texas for a couple of months; he will be back before the summer. So for spring break I am going to get a flight out there for a week. He doesn't know this though, and I'm not planning on telling him. I want to surprise him. He is going to school while he's up there, and I've already talked to his cousin about what all his classes are and what rooms they are. He already had his spring break in march, so when  I go up there he will be in school which is perfect. I'm going to go up there on a Sunday and his cousin is going to show me where all of his classes are. So I'm going to get 7 big poster papers, because he has 7 periods. On each paper I'm going to stick on the front of each of his classes and write, WILL. YOU. GO. TO. PROM.WITH. ME. and the last one will have a "?" on it and I will be standing in front of his 7th period class holding it, and when he sees me he will know that those signs were for him. I already know he will go to my prom with me because I asked him before and he said of course, but I just want to do it in a cute way, and I think it will really surprise him. So that is what I'm planning on doing for spring break.
