and now for best drama...

So the van is MIA so I am driving my mom to and from work for the while.
I drive my sister to school every morning and have been since school
began last fall. As you may know I drive a 2001 dodge dakota with a 4.7
liter V8. It makes impressive power and has great performance.... With
one downside. It gets about 15 Mpg.
So anyway, we just got back from a trip up north that put somewhere in
the neighborhood of 100 miles on the truck. Also, last thursday my mom
helped drive my sister's class to their fieldtrip in the city. So that's
a good 200 miles on the truck that frankly I had nothing to do with. Not
to mention the 1 mile-or-so a day trips to my sis's school as well as
the regular trips to my uncles house, the store and any other place we
have to go. All said and done I get paid 80-120 dollars a month to drive
for work. It costs me about 45 dollars to fill up and I have to do that
about every week. So, I'm gettin reimbursed for a little over half of
the miles driven on the truck. While the other half, the half that
usually has to do with crap I have nothing to do with, comes out of my
pocket.
It seemed fairly reasonable to me to request that my mom fill up the
truck this time around. She saw it differently. She proceded to rant
about insurance and car payments that she thinks she should be charging
me. And even mentioned rent. Now, I get paid 10 bucks an hour for a job
that I do only about 3 hrs of work a day. I can barely afford the damn
gas and she thinks I should pay for more stuff? With all due respect,
its her name on the car purchase, I didn't get it. And I WOULD pay for
insurance if she would only pay for her share of the gas. As long as I
am the only one paying for gas, she won't see any insurance money. Which
is a bargain for her since insurance is like 35 a month and I have to
pay for about 80 bucks of gas out of pocket. BLAH! Damn it all.
