if that older person wants good for you but has in some misunderstanding or using wrong way..then you need to represent yourself in cool and right way.........and if they are using this behaviour just to tease you or hurt you its mean they cant be your own bcz our own can never do this{may some time they use wrong way to understand us}.....so then just ignore them all or make them sure that you are mature and can thing right and wrong ......so plz dont do this in future...

life is a struggle !

It depends who this older person is. If he is your father, relative or employer, you still need to be polite, but you don't have to agree with them. This person may be ill, you never know.

I'm not sure I know exactly what you mean. I would not respond at all to the person. By the way, well has two "L's" in it.
