I remember with nostalgia the old 80's game "Hungry Hungry Hippos" that my little sister got and we all played...
I remember the minor annoyances of the game: too much noise from the game itself, the game gets a bit rowdy (kids making their own noise) which might annoy the parents, marbles left all over the floor, marbles as a choking hazard, one or more hippos malfunctioning, etc.
These problems of the game I was well familiar with.
However, the biggest problem wasn't an issue before today. There are only FOUR hippos. What are all your other kids going to play? Baby Boomers would say, "WHAT other kids?" as they (as a generation) maxed out at 4 children; perhaps 5 on rare occasion.
Nevermind the fact that nature generally gives a couple more children than that, assuming average fertility, nothing is being done to "prevent", the husband doesn't spend half his married life deployed overseas or out of state on business trips, and you didn't get married in your mid 30's.
It never once crossed my mind, until today, that 4 hippos wouldn't be enough. None of the kids wants to volunteer to "sit out" this round.
