for 8 years I've been hanging out with my friend, he has a cute sister and I really like her she is a year older then me but every time we talk she always seems to laugh and always ovbserves me. And I realized that I am in love with her.. well if u call it love lol :X so I need some advices T_T so please guys n girls help me! Oh you by the way I'm 17 n she's 18 and I want to make my move on to let her know that I'm here to see her not my friend when I come over her house and a way to ask her out :o

Be honest.
That's mainly the ONLY thing you CAN do.
Girls like me ALWAYS love honesty.
If you two have that... then you have EVERYTHING!
It's meaningful.

Watch out for your friendship and maybe see if she wants to go out for a walk where her bro won't be there
