How about 36?
The folks who say “oh, that means you’re only…” when they find out someone is born on Leap Day are probably not TRYING to be mean, but let’s think about this for a moment. Calling an 8-year-old “two” is kind of hurtful, because they’re finally coming into the full flush of sapience, and are now being told they’re a toddler. Calling a 12-year-old “three” is rotten, because they get accused of being babies any time they complain about something. And calling a 16-year-old “four” is simply bad form because calling a 16-year-old anything is like shooting depressed, teenaged fish in a barrel.
