My school sells roses for Valentines Day. What do I do if I get one from someone I DONT like?

Since Valintines Day Is cumin up I'm alittle worried. I'm new to my school I've been here for 2 monthes. My friend told me that the club she's in sells roses for Valintines Day. Now like 2 or 3 boys in my class have a crush on me. I can just tell. The problem is I don't like them like that! 1 of them eats EVERYTHING he can get his hands on. So I really don't like him. I kinda like this other boy in my class. He's sweet and funny. but also his friend ( I think he might have had a crush on her idk ) just had her last day on Friday. She's moving to indiana. My friend is gonna tell me if someone buys me a rose. I'd like for my crush to buy me one but no one else. It's gonna be embarrassing if my friend hobbles ( she's on crutches ) into the room with half a dozen roses for me. Im not even the prettiest girl in my class. What do I do? Should I have my friend throw away the roses on her way to my classroom? Please help! I'll die of embaresment from the mean girl if I get tones of roses and she finds out! ( 2 of her cousins are in my class ) what do I do? No I can't drop out of school or transfer schools. Please answer ASAP!!!!
