I know what you mean. it's really a shame people act like this, if you're not married you're a child, you don't count. it pressures people into getting married when maybe they wouldn't otherwise.

then, though, someday you might get married, and then you won't be a adult because you don't immediately have kids!

my husband's family takes the infantilizing cake though. last christmas they dressed up as santa and mrs. claus and went ho-ho-ho-ing all over the house. there were no kids there. there was nobody under age 30.
