Oh! You are a 18 year old girl, you sure can be trusted with marriage and having/raising a kid but you sure cannot be trusted with booze!!
You may want to lower the drinking age but you need to come up with better reasons :) Also why shouldn't the drinking age be 15 or 13?
What they don't understand is that, the more you restrict/ban stuff, the more people get fascinated and attracted by it.
Most of the stuff does not make sense either. However, it is not just India. For example, gay sex is banned in Saudi arab too.
