How can i give my crush roses?

[Brad]

I really like a girl in my class, we never talk, but we know each other from 8the grade. I was mean to her in 8the grade but I think she forgot about it because she doesn't give me that "I hate you" stare anymore. I really like her and I want to give her flowers and tell her that I have a crush on her but I can never seem to get her alone. In class she comes in and talks to one of her friends who sits exactly behind me,and I tried to tell her then but the teacher made her sit down. I can't tell her after class but I can never get her alone, she is always with her creepy best friend who has a stalker crush on me, and I do not want her to think I like her if I had her the roses to give to my crush. How can I give the roses to her and tell her that I like her without these interferences?
