The early bird gets the worm
Showing up early for a doctor’s appointment is, in our opinion, not a problem. In fact, you should expect to wait around the doctor’s office for up to an hour (or two) as doctors are very busy people. But what annoys us than driving our parents 30 minutes early to a doctor’s appointment is knowing that the doctor is almost always going to be late.
If you thought that was bad, have you ever driven your parents to the airport? Their flight might be scheduled at 1 PM, but they’ll force you to take them to the airport at 6 AM, just because. And you can’t just leave them at the airport because you’d look like a jerk.
