talk with them.
talk about your garden, talk about traffic, talk about how one time you went to band camp.
keep them on the phone. talk with them while flushing the toliet and grunting.
Talk with them, pause and yell "dammit, I told you NEVER to touch my TV remote, your whore".......... then go back to talking them.
Ask all sorts of questions, but must of all, TALK TO THEM.
they will stop calling.............
