Insult

If you really want to insult someone, all you have to do is refuse their offer to help, provided they are capable of being real help. 

Sometimes it is best to explain that you have to learn or need to do something yourself, rather than telling someone no, to an offer of help.  To just refuse help is to say, "I don't need you," or "I don't want your help."  Conversely, to ask for help is a compliment.

But, when you refuse help, you may get an opportunity to really mess up something and make mistakes that could have been avoided, if only you had been smart enough to take the help.
