Is this normal to show how close you are with your brother/sister?
I was with my sister's and a bunch of her friends last night when a completely normal conversation turned slightly less normal. I'm 19 and a guy and my sister is 18. Somehow we were all talking about who we are close with and my sister and I said how her and I are close.
I don't normally hang or talk much with her friends so maybe that is why they were kind of surprised to hear us say that. Like my sister is my best friend pretty much and we do a lot together and talk about all sorts of things.
Anyways, my sister was explaining to them how close we are and they didn't buy it so my sister said aloud how she had no problem with me touching her boobs to prove it. They were all like I dare you, I dare you to do it and of course I had no problem doing it because we are really comfortbale with each other so I did it and held on for like 5 seconds or so to prove it was cool.
My sister just gave a little sneer and smile to everyone who didn't believe her and they were all like well I guess we were all wrong.
What do you guys think of this?
