I have had the date/ time mix up 3 times over the years. Twice she called me because I never miss and if I will be late I call her. Once I was close by and arrived about 20 minutes late; had most of my appointment. Another time I was at a kid function so couldn't just leave. Rescheduled for another day. One time I thought my was earlier than it really was. Showed up 2 hours early. Her sometime for time arrived wasn't there. So she took me in with the understanding I'd the person showed to late I would leave and come back. The person showed up about 15 minutes late.
