Stop looking it will happen then, just relax and enjoy yourself. Girls like dudes that look like they have there stuff together. Have fun with your friends, don't think about chicks and the next thing you know she might just tap you on the shoulder. Use your humor but don't be too goofy, and let her see your serious side aswell. Take care of yourself and love your grandparents for letting you stay with them, they deserve your thanks and love. What ever you do don't fall in love with the first chick that shows interest, or you know "wink wink". live a little.
