Your idea of cheap may not be shared by your folks. At the same time, there are things that you just can't resist. So, what do you do? Well, if you are financially independent, don't tell your parents how much you spent on shopping. 

Your fashion sensibilities may not match, but be diplomatic when your parents gift you something that seems to be straight out of an 80s' movie. Ask for the bill and exchange it discreetly. When they ask you about the dress, tell them that you loved it and have kept it aside for special occasions. 

Most children love it when their parents are away for a few days — that's their chance to enjoy newfound freedom. But it is better — for them and you — if they don't know that you have been waiting for them to leave. 

Most parents like to believe that their children will never overstep the line, especially when it comes to smoking and alcohol. But the fact remains that whenever they get an opportunity, the younger lot make the most of it. If you are high on alcohol, don't announce it at home. 

It's great if you can talk to your parents about sex, but there's no need to burden them with unwanted information. Keep your dates a secret if you want your parents to let you out of the house after sunset. 

In a situation like this, most mothers would say, "Why can't you have coffee at home instead of a coffee shop?" But there are times when you just have to visit that coffee shop. Your parents will freak out if they know that they could have done their grocery-shopping with the money you spent on coffee and some sandwiches. 

You were short on cash and decided to borrow some from your folks, and forgot to mention it to them? Well, that's not on. Even if you don't tell your parents, promise yourself that you will never do it again.
