If she wants daily car service, she should be willing to pitch in for gas and parking. I am certain that somewhere at your school there is information on the bus routes and schedules as well as a listing for people who want to carpool.
I don't drive, as most people know. It's not for want of trying; I've had dozens of lessons and spent hundreds of bucks. My hand-eye coordination is terrible and I just can't manage. No matter what I do or how many instructions I'm given, I just cannot make the car do what it's supposed to (really annoying, disheartening and plain frustrating for someone with an IQ of 130 who can usually do something the first time). My last driving instructor finally said, "Just stop wasting your money."
But I live in Johannesburg. Those without cars are pretty much scr3wed. I get a lift to and sometimes from school from a friend, #1. I get a lift from school sometimes with another friend, #2 (we all work at the school and I live on both their ways home). I make sure to give friend #1 her a thoughtful gift every month or so, and about twice as much petrol money as it actually costs, towards the end of the month (she's a struggling single mother). Occasionally I will ask her for a lift somewhere and if she's not busy she will agree (today, for example, I had to go for an ultrasound -my doctor suspected cysts - everything's fine - the hospital is only half a k from my house). I made sure to let her know that I really appreciated the hour she spent taking me after school ended.
I help friend #2 out by doing tasks at school that she'd normally have to do (changing towels in the bathroom, buying soap, shredding, copying, etc), getting her thoughtful gifts and giving petrol money. And making darn sure that she knows I appreciate it. And whenever I need a lift I do not say, "I need a lift," I say, "Friend #2, would you be able to give me a lift this arvie?" And if not, she'll tell me and I can organize with someone else.
I am always conscious that the person is doing me a *favour*. I can't get over people who just expect others to drive them around with nary a thank you.
I am very conscious of the fact that someday my lift sources may dry up. Then what will I do? I will learn the taxi system! Most people are shocked when I say this because taxis are used almost exclusively by black people (not taxis like New York ones, these are mini-buses that hold 20 people and most are operated informally), but if they can rely on taxis, so can I.
My bugbear is when people berate me for not knowing how to drive and say, "You need to learn to drive." REALLY? Until you pointed that out, I had no idea that driving was important!
