Should i tell my sister's friend that i like him?

Mysisters guyfriend is the hottest guy I ever seen!!but i don't know if he thinks the same about me. Atround here you only date people who are pretty. But i don't know if I am that girl to him. Should i just tell him how it is or should I leave him...

alone? There is also one year of an age diffrence.

thanks

well my neighbor is one of my best guy friends and i think he is the most hottest guy i have ever seen. weve known eachother for like 12 years and i want to tell him how i feel but i dont know what to do. i told my best friend and she told him for me and it ended up he felt the same exact way. we ended up just hooking up and just staying friends. bt listen tell how you feel!! =]
