In fact, I don't mind long periods, it's not that i am in a hurry. As long as this doesn't make people lose motivation and we get the rounds up at reasonable times (like a week). However, this is irresponsible. If you take up on a responsibility, you should be doing the minimum requirements of it. Otherwise this can cost you some self respect and may turn into a bad habit which also annoys people around you and lose their trust.
