How old are you, sim dude?

Would be fun to be able to ask the age of a sim. Like, "I'm and adult, and I've still 5 days to go before turning into an elder."

I know, it's too late now, as the game is done, but I'm always stressed when my sim asks someone in marriage.

I tried to move the future groom in the household before tying the knots, but the "move in" interaction didn't show up. I wonder why... Their relationship panel was full.
