Is it normal my female friends like my little bro?
Ok, so as it says above I have quite a few girls who are friends that I talk to on a regular basis. Now it has come to my attention over the past couple years that in stages some of the quite attractive girls of my friend group have had a crush on my brother... Now under other circumstances I wouldn't mind but the fact he is 13 and we are all around 18 (some of the girls being 17) I find it really weird hearing "He is gonna be really hot one day (soon)" and "I really enjoyed his company when I was doing work experience at his primary school... I almost cried when he left" (bearing in mind she was probably around 15/16 when she was doing the work experience)! Now I really need some advice on this, is this just natural (as they see me in my brother but as I am a friend I am 'off limits' or something)? Or is it something else that I am being ignorant of? I really don't know what is going on here and I am finding it really weird.... Is it natural to find it weird or should I just be accepting of it but respond with a friendly "I can't stop you liking anyone, but FYI he is still my little bro... So he is off-limits to you"?!?!
Thanks for any help in this 'issue'!
