I am very fortunate in my friends, that I have at least three people who I could've called upon to give me a ride to the dentist (not counting Adam, because he'd've had to take the bus home and might not have gotten here in time). But, in the moments after my tooth pretty much exploded, after I determined I needed to get to the dentist ASAP, called the dentist, and called Adam, I had three people on my shortlist of "people I know will come and take me to the dentist in the middle of the afternoon if they're not doing an emergency thing for themselves".
And that's a good place to be. Not that I ever want this to happen again. But having a bunch of people any time of day or night (because there are other people who can and would help evenings, weekends) who would take you to the dentist is a good thing. Healthy community.
(I can't drive because
a) I don't know what drugs I'll be given
b) my last seizure was two months ago, so I'm not street-legal for another four
c) Stress and sleep-dep are seizure triggers anyway, so even if I was street-legal, it wouldn't be a sound risk.)
