Advices. Are they free?

The world is filled with varieties of people.Some sweet,some sour,some bitter,some salty and than there are some who cross my tolerating taste limit.

I call them "FREE ADVISERS". Even if you don't need any they give it for free,anytime,anywhere.They are all over,I bet, you surely find one in your world.

They always advice you to not do anything, that your doing,to do it in the other way and not the way your doing..they sometimes even go in the way of doing it and showing you saying.. see that's how it is done!!

Hmm just one question..
So,why didn't they do it before? :D
