[header] How to make yourself at home [title] Accept the compliment. [step] When someone suggests that it's okay to " make yourself at home ", accept that they really mean it and take them at face value. It's actually not very polite to expect the host to wait on you hand and foot and to keep providing you with permission once they've made it clear to treat their place as your own. 
That can become trying on the host very quickly. So, be at ease with the fact that they trust you this much and are happy for you to help yourself.
