<human>: Can you provide a brief overview of the text?

Lexy and I have been friends for about 3 years now. I'd love to hang out with her more and do more stuff with her, but she lives with her overbearing parents 30 minutes out of town and shares their car; I pick her up often but she really hates it. Almost as much as she hates the words "my treat."

We're both college students, but I have a pretty good job that pays well enough and not that many expenses. I'd like her to go on some of my trips or come out on the town with me sometimes, but she refuses to do anything she cannot afford -- and this girl is the cheapest girl I have ever met in my life. She absolutely refuses to buy anything unless it's price slashed down to nothing. She goes for the absolute lowest-quality stuff constantly, even if she'll just end up replacing it the next week because it was trash. She doesn't like getting rides off me or me offering to cover costs; if she relents, she always insists on covering the next outing, which results in us throwing rocks into the ravine behind her house again. 

It really is nothing to me, it's only occasionally after all, and I just want to hang out with her someplace other than her house, where her parents stare at me weirdly and they all talk constantly in Spanish so I can't understand. I don't know why she's so intense about it, my policy is, if someone offers and *tells you not to worry about it,* then it's fine. How do I get her to chill?
<bot>: My friend hates it when I give her rides and offer to cover costs of eating or drinks. But if I don't, we would literally do nothing all of the time. What do I do?
