We adopted our grandson, and he is very aware of the why he came to live with us, and has a wonderful relationship with his mom and dad. . .one day we were in the car and we were talking about his big sister, and why she wanted to be with her dad so much. I said that she was "his baby" and she was old enough to remember the good times before the bad times came to pass. He sat there for a few seconds, and then looked at me with these great big ole' brown eyes and said, "OMG, are you telling me that Dee was in our dad's BELLY??" I laughed so hard I almost had to pull over, because I am one that just absolutely splits my sides when something hits me funny. I said, "NO, NO! Nothing like that, I just meant . . . ." and he laughed and said, "Oh, I KNOW what you meant, you just meant that she was "His little baby" and he made cradling motions with his arms. That was 2 years ago, and I still almost get in the floor over it. It has become a family laugh-a-moment now.
When one of our DD's was about 10, someone had put a sign out that was tall and slim, so they had to split the word in half. DD was reading it as we went by, and said, "Free Pup Pies". The owner had written PUP on one line and PIES below it, so she thought he was giving away puppy pies. We laughed for months over that one, someone just mentioned it to her not long ago at a get together.
Our youngest daughter was looking out at the sky when we were coming home late one night, when she was about 4 and saw an airplane flashing overhead. She wanted to know what it was and I told it was an airplane. She mulled it over for a few seconds and said, "huh, wonder why they want to take our picture!?" I laughed for weeks, and still to this day. She just turned 30, I still think that was the funniest thing.
