When my son was about 2 years old, he absolutely loved The Power Rangers. We were at the mall one day and asked for money to put in the Power Ranger bubble gum machine and as his prize he got a big gaudy Power Ranger ring, which he promptly placed proudly on his finger. Later, as we were walking though a store, my son standing in the basket of the shopping cart, we passed by another mother with a young boy in her shopping cart. As we passed, my son held the hand that was clad in the Power Ranger ring, up with his little hand fisted....the little boy in the other cart promptly hed his fisted hand up in a sort of return salute and they stood that way until we were well past each other and then on cue, they both lowered it. As the boys passed each other, they both uttered "POWER"! They didn't know each other nor had they ever laid eyes on each other, but it was like this secret signal that only Power Rangers knew. It was halarious!
When my eldest son was nearly two we were out shopping when he announced that he had to go to the toilet, and I suggested to my husband that he take him into the mens toilets and show him how to use the urinal.
My husband went first and when he finished, my son clapped his hands and said, "Well done, Daddy; you did that all by yourself!"
