When I was around your age, I experienced this horrendously! It was like: meeting me for the first time and thinking, wow this girl is really nice and then, another girl comes along and suddenly, I am ignored and due to my childhood issues, I have never felt comfortable around my own sex and I tell you, if I go into a public toilet, even today, at nearly 45, I go in and come out straight away; you will never see me standing gossiping with other girls and touching up my make up or hair!
I thought I was tons better today, but just this year, I went to a concert for the first time ever, and on my own, to see Taylor Swift and honestly, I might as well have gone back to my teens, for seeing groups of girls absolutely FREAKED me out and oh the shame, when trying to find my seat and having to go past them, which they were fine, but ya no, a case of just a throw look and getting back to what they were gossiping about! So, I look at my ticket and realize with sinking heart, that I read the wrong number, which meant, that I had no choice but to go back and this time it was a case of looking down their noses at me (which I don't really blame them) and one saying in a very haughty voice: can't you go that way; I don't want to move my things again! I knew I was worthy of being scorned, but it did not make it any easier to bare and when I finally found my seat, I am afraid I sat down and tears just escaped but thankfully, due to the darkness, and the fact that no body card, I got away with it and then, this couple came to sit next to me and the woman bent down and said: I think you are in my seat and again, I could have died to see that yep I got the blasted wrong seat again! Amazingly and thankfully, her husband said: does it really matter? We have seats and she just did a sweeping motion with her hand and said: no guess not and the relief that I felt was enormous. You see, I did not appreciate how awful the stairs were and I am such bad balance, due to always falling over, that it was a complete nightmare, but Tays made up for it, because she blew me away and I was shocked to find me standing up and dancing and singing!
I finally have some girl friends, but I will never feel completely at ease with my own sex and yep, I love men and rather their company any day!
