MD - I definitely want to be alone. Long wait time in general, but patients are never informed. Me or the other person wouldn't know how long the wait is for the MD and then payment.

I suppose I would want someone to drive me if I needed surgery under general anesthesia, but then I don't have anyone. I took public transport after my wisdom teeth got taken out under general anesthesia, after lying to the nurse that I'll call for a taxi.

For emergency room, I have no one since I live alone currently, but I likely would want my partner. Close friend sounds tempting but I'd feel like a burden, so no.

I've never had to put down a pet, but I would probably want my partner or close friend around, as long as they don't push me to talk. But then, I hate crying in front of another person lol.
