How to tell parents about a girl I like! (please help)

Hello I am a 18 year old a Senior in high school. There is this Freshman girl that i like alot and she is 15 2 1/2 years younger then I am. I was wondering how I am supposed to break to my parent that I like a girl. I mean its jsut my main fear. Everythign else will go smoothly but thats just the main problem i have.

Hi, Its difficult to have conversarion with ones parents about this kind of matter but if u dont talk about this right now then might be u never get a chance to talk about this with ur parents.So all u need is courage.Try to talk with ur parents about this when their mood is good. Have a gr8 destiny. Take care.
