There's something powerful about the words or phrases involving wet pants.
So many of my memories involve the question being asked, "Have you wet your pants?" Or "Why/when did you wet yourself?"
Not just memories of grown ups either. Memories of playing with other kids and someone said " I just wet myself!" Or "So-and-so wet his or her pants today."
I remember my aunt calling my cousin over while we were playing and asking matter-of-factly "Did you do a wee in your knickers?," my cousin denying it, and my aunt putting her hand under my cousins dress to check, and finding wet undies there. It was no big deal. She would just remove my cousins panties, dry her legs, and get her to step into a new pair so we could keep playing.
As a teenager, I was at a friends place one day and his 7 and 6 year old brothers were playing outside in the front yard, both wearing old grey school shorts, and both with big wet spots covering the front. Even though these kids were to old for that, they didn't care in the slightest. Neither made any effort to hide it, and were even running up and down the street playing. Both kids kept grabbing themselves and checking out the damage, but were completely unconcerned by it.
When we went inside, my mate told his mum"The boys need clean pants again!" His mother just sighed and looked out the window. She then went and got a towel and dry undies.
She went to the front door and yelled out "Have you two wet yourselves again? Come here now and get changed!"
The boys ran up to the front door, and while standing outside on the step, she just removed their pants, dried them, and put clean underpants on them. The older boys undies had a big poo stain in them as well, but that wasn't mentioned. She told them that they weren't going to get new shorts, because she was sick off changing them, and they would have to put up with wearing just underpants. They didn't care, just ran off to keep playing.
I was only there for another hour or so, but when I left the younger boy was wet again. I asked my mate later and he just shrugged and said "They always piss their pants!"
But I digress.
I just find that reading or writing the words is fun, but actually hearing somebody say them out loud really gets a reaction from me!
