My Parents part 1: My Mother

My mom grew up in Pittsburgh, Pa with separated parents.
My grandmother who was the youngest of 13 children, dropped out of high school to help support the family so, when she split with my grandfather she had to work in factories and low-skilled jobs to try to make ends meet. She never drove, so my mother had to walk everywhere or take the bus. She missed out on many many opportunities and parties as a child because my grandmother didn't drive.
Now I love my mother very much, and appreciate everything she has done for me, but her childhood has left her bitter.
So whenever I ask her to pick up my friends, or take them home she sighs and it goes a little like this....
This is unfair, they need to pull their weight, how come their parents aren't coming to pick you up etc...
And this leaves me....feeling guilty
I feel bad whenever I ask her to take me anywhere, and when I have to pick up a friend. I don't know if my friends's parents just don't feel like driving their kids, or if they honesty can't get a ride. And quite frankly, when my friends's don't get a ride with someone else, they don't go...which also hurts me because I don't get to hang out with them. Is this a matter of pulling one's weight?

But also whenever I call my mom to pick me up somewhere, and she has to wait for me to get out....I always end up getting yelled at.
And it goes like this....
How come I'm the only parent that ever has to waitt, other kids wait for their parents. What took you so long? Do you know I've been waiting out here for X amount of minutes? I could be folding landry, or cooking dinner, I don't have time for this!

Now I love my mother very much. And I know I must be at least a little spoiled...but a big part of me is just so glad that I have my liscense now, and really really wishes that I had a car. Not for the sake of having a car, but so I can be independent...and not have to ask for my mom to take me all over. I tend to be stir crazy, so I get depressed whenever I stay in the house all day long. And take it out on her all the time, to take me somewhere.

But whenever my friends want to get together and they ask me for a ride, I get this knot at the bottom of my stomach, because I'll have to ask my mom for a favor....
and I know she'll ask, "why can't their parents take them?"
