act your age

okay heres what you ask when some dick bit tells you this one if this is something i should not be doing at my age then when? and why is this not for my age to do? like a parent scolds their kid for mooning some one and they say act your age hell hes being groan up i see college kids do that all the time and you know you'll never seen a parent tell there 9 year old boy to act his age and stop doing homework and play with friends or tell their 16 year old girl to act her age and go out with a guy her dad hates because when people say act your age they mean act the one i want you too they just put the age thing in to make you seem like the bad guy.
