Am In Love With This Girl And She Happens To Be A Friend Of My Junior Sister. We Have Never Spoken Even When She Visits. Please How Do I Ask Her Out?

The first thing you need to do is just say hi to her when she comes over then start to build up a conversation make sure you keep talking to her and dont let an awkward silence come on if it does just think of a simple question to ask like 'do you like xfactor?' or something like that. After a while tell her how you feel and ask her out. I know its scary to ask someone out but once you've done it you feel loads better!!! DON'T ASK HER OUT BEFORE YOU'VE HAVE HAD A PROPER CONVERSATION she hardly knows you so you do need to get to know her first but just relax and keep talking to her GOOD LUCK!!!
