You can refer to a person aged 20-29 as a young adult.
I would call a 20 year old 'mister'. He is beyond boy, in my opinion.
Yes, at 20 she/he is an adult and she/he can date a person who is 49.
Yes, a 20 year old and a 28 year old person can get married to each other.
Right now, it is 2013, so if you are 20 years old, you were born in 1992 or 1993. In general, if a person is 20 years old, that means that they were born in the year (this year minus 20) or (this year minus 21).
If your 20 your old enough to call an insurance company .
i don't know who the shortest 20 year old is, but the shortest 18 year old is 22 inches - 56 centimeteres. He also claimes to be the shortest person in the world. I also know that there is a 21 year old that is 29 inches tall/small.Hope i helped ;)
dont see how this applies to teen dating but uh... Wouldnt this person be 20 years old? kind of a redundant question.
If the otherwise underage person has parental permission, then they are allowed to.
Call the police if that's minor age in your state.
A 20 year old
