Friends?

I have these friends 
that are in my life
but all they do  is
cause me strife.
I can't walk around nude,
when I'm home alone
because they just walk in,
they don't even phone.
They just turn up
whenever they like,
I should really tell them
to take a hike
but oh no,
what do I do.....
I say... hiya buddy,how are you?!
Then they get comfy and
watch the T V,
whilst I'm in the kitchen
making them tea.
You know,all of them do it,
every single one,but just
where will they go...
when I am gone?
