It is true that that we have big big universities and libraries. But the more we learn we loose ours sense at least to understand the root of a silly problems like this. If we need to solve an issue first we should find root of the problem. I still do believe that women can play a vital role to stop such teasing by keeping a modest dressing code. Ok, even if men do not touch you, do you think that they enjoy with their eyes. Who can stop this?. Ohhhhhhh....I see....I forget..it is not a problem at all for a women who want to be prostitute.
