It depends on who you ask. When I was 18, I hung out with older people and I thought the 22 year old girls were so so old. Now I am 45 and think of 25 as a kid, but realistically, 25 is not a kid. 25 is old enough to know better, not to hide behind the excuse of being young and stupid, old enough to be legal in every way in every state, old enough to be responsible for your own actions, be in the military, vote. If you had a baby young enough, like age 12, and they did the same, 25 could be a grandmother!
