Tonight I worked a little late. I left the office at 7:30 p.m. and headed to Subway.The young woman behind the counter said "how was your day?". I said "pretty good, but I had to work late". Then I realized, and said "Oh, but here it is even later and you are still working". She said "and I have school tomorrow". I realized I should be grateful that I work at an interesting position while others work later making sandwiches before going to school the next day. I should also avoid complaining, ever.
