I thought I only had two hours in Houston tonight, but it turns out that I have FOUR, which is plenty of time to get off airport grounds for dinner... but all three of my friends in Houston are busy or away. I like to enter my events in my Google travel calendar by including things like "1400-2000," which Google is smart enough to interpret as 2pm-8pm (automatically setting start and end time). But I also like to confuse "20" and "22" when I'm thinking in 24-hr time, which is why I thought I only had 2 hours instead of four.
Wish I had checked the actual itinerary earlier! Sorry, guys. I'll be the one sitting at the airport, alone.
