Give her a funny birthday card.
You talk to your crush not making it obvious you like him/her if you do or if he/she knows. Just talk to them as if they are one of your friends and don't make things akward.......
Just ask them if they would like to go to dinner or movie later. Let nature take over.
say hi a couple of random times if he looks at you LOOK at him IN THE EYES
Yes.
A romantic bouquet of flowers with candies is a perfect gift for your crush birthday.
isn't it obvious
I think it is pretty obvious he is out with Selena Gomez
There are many sweet messages that you can say to a crush on his birthday. One thing you can say is " I hope you have a magical day."
.
Send them a message saying 'happy birthday' maybe?
Yes. This is because if she REALLY likes you, she wont talk to you in fear of making a fool of herself.
No. Naruto does not have a girlfriend but he does crush of Sakura and there is something between him and Hinata, who has a rather big crush on him. It is obvious that he cares about Hinata and he crushes of Sakura. But, no, he does not have a girlfriend.
