If you like someone yet you are to shy to tell her, try been her friend. You can do this through constant communication like text, call to see how she is doing. Once there is a strong friendship bond you will have a better chance thus easier to say.
If you like somebody and don't tell them then there is the possibility that somebody else will express their own feelings for the girl. Then she will be dating somebody else and you will be back here asking us questions about how you like some girl but she likes somebody else. My point is Just Go Tell Her. If she laughs no big deal
Don't worry! Everyone has probably been through this! I am a girl and I would understand if a guy liked me and he is shy. Sure it'll take a lot of courage, but just tell her when you're ready and comfortable! I been through this (telling a guy) and everything will turn out fine! If you don't tell her you'll never know!!
I think you should tell her, Im a girl and I think its the cutest thing when guys are shy like that. Honestly tho, tell her how you feel. You cant live life with regrets you have to take chances otherwise youll never know. Nobody wants to be asking "what if" when their older, so tell her how you feel
