Is it normal for a sister and brother to squeeze/slap each other's bum
Today my friend told me that she and her brother used to squeeze each other's butts. I thought it was strange and my friend could tell I thought this so she tried to cover it up by saying it was more of a pinch and slap than a squeeze. I asked her at what age she and her brother used to do this because if it was when they were little you know kids don't know any better and they find that kind of stuff funny. She kind of hesitated before she answered and said it was when they were younger but I don't believe it. I think it was until fairly recently. She is now 26 and her brother is 22.
I come from a family of sisters so I don't know is squeezing/slapping of butts normal behaviour between a brother and sister? When I was little my sisters and I used to joke around like that a bit but we're all girls and we definitely don't do that anymore because we're all in our 20s.
