out why they say............? you are too immature to drink but you are able to sign a legal contract of almost any sort..or your not a minor anymore when you turn 18 but if you get a underage drinking ticket at 18, 19, 20 its a MINOR in possession.. To me honestly it should be raised 21 to be a legal adult i seriously don't feel like an adult and it doesn't seem like there is that much time to grow up from 18 to 21. It should be everything 21 or everything 18 plain and simple i feel like you should be considered a minor till 21...im probably the only one
