I remember similar situations
The booths, public bathrooms, the "gangsta" look while driving, etc.
I'm only 5' 2", so when I was pregnant with my twin boys, there was very little room for carrying them. I went from a 28" to a 56" waist, and I'm only 62 inches tall. Not to mention they were both transverse (side lying), so from the front, I looked like a gigantic football.
I was due in February, so to appeal a bit more to dh, I decided to paint my belly (body paints) to resemble a football. He had a Super Bowl party with all his friends, which I attended as the human football.
We had a little tikes football-shaped toy box set up as an ice chest in the living room, and the guys would jokingly reach for my belly to get their beer.
My middle son would seek shelter from the rain by standing under my belly at the bus stop.
At 5 months, I looked 9 months so for months on end people thought I was due any minute. We lived in a very small town way out in the middle of nowhere. People would ask when I was due, and their jaws would drop in shock when I said I had a few more months to go.
I became very tired, very quickly of people asking if I was over due, so I would just reply, "Yah, the experimental drugs are working well. If I keep taking them, I can carry the baby until it's out of diapers."
But the absolute funniest thing happened to me at the grocery store, shortly after they were born (they were about 4 weeks old).
DH was on deployment, and so grocery shopping meant taking a ride on the "baby" train. I'd snap each of their carseats into the seat part of a cart, push one in front of me, and the other behind, as I was making my way through the store.
Now keep in mind we're still living in Small Town USA. One could clearly see (or at least I thought) that the twins were twins at 4 weeks old. I was approached by a spunky elderly woman, decked out in her Sunday Church attire. She came up to each of the twins, and was OOOOOOing and AWWWING over them. She then turned to me and said, "Giiiiirrrrrlll . . . you must have had pregnancies BACK-TO-BACK!" She then looked down at my belly and asked, "So when is THIS one due?" OMG
