I'm going to hide away whenever my extended family visits
What is your reason for hiding from your family?
I don't like to be around most of them.
Family can be too much but you shouldn't hide from them. It is rude and people will be upset and feel hurt.
I will avoid them mostly and oh, nobody cares about me anyway.
When you have people coming over to see you, hiding from them is just not very kind. Whether you like them or not, you owe it to them and yourself to at least greet them. Not only that, but you do not want to get into the habit of avoiding things you do not like in general.
