Elevator, just to bother IRL people who give advices (sometimes totally unrelated to what you're doing) when you didn't ask any.
Once a dude told me to take the stairs because it was better for legs. First, with my knee joint problems, it's not. Second, I don't know why he told me that, I wasn't going to take an elevator, I was just thinking about what CDs I would rent and felt good and everything. Then he laughed at me, an ironic laugh, for some reason. Still do not understand why. Mind your own business, asshole. He made me panic because I really did not understand, and now he probably forgot about it but I'm still stressed thinking about it, especially because of the laugh which was clearly mocking me and not a real laugh. It seems silly but in context you'd probably have reacted the same way as me. I hope he leaves kids alone, now.
Also, elevator so when I have walked for most of the day, I can stop. With the state of my joints, no, I shouldn't use the stairs or walk as much as I do sometimes. I walk that much because I don't have a car and sometimes don't have money for public transport and want to avoid getting caught in it without having paid. So I can take the elevator, damn it! Thankfully, most days, I don't have to walk around or walk around that much.
