It's My Time

I have a relative, who calls and gets a buzy signal because I'm online, so knows it's my day off, then gets pissed off I don't get off-line so they can call on the phone.

I'm trying to get a bunch of things done, like fill out apps, n looking things up for research I need in projects. Sometimes I'm contacting old friends. It's my free time, on my one day off, but they want to tell me I need to do what they want. This happens almost every week.

This person gets on the phone and talks for hours. It's never a short call. On week-ends they are wasted and it takes a great deal of patience to deal with them. But I don't want to start a war, I just want to use my time as I want, not be on the phone all night because they figured out I'm home.
Excuse me, it's my choice, not yours!
I don't have all night!
