Or rather how do I get out of this lift share?
I'm sharing lifts to work with a friend (each take turns using our own cars). It's just not working for me: she keeps a slightly later work schedule than me for starters, and then often runs over. I'm lucky to have a job where I can leave on time most days so I can get home half an earlier if I'm alone. Especially in summer that's a big deal for me, as. I get depression in the winter and want to make the most of light evenings while I have them.
The only problem is, it would obviously increase each of our travel costs, and I think she'd be annoyed with me.
How would you go about 'breaking it off'?
