What's even worse is when you bank on an auction going late into the night, then come back to check on it and place your bids only to find out it's already ended. Oops! Doesn't happen often, but I missed out on several photos in an auction recently because of that.
Another lesson for me to not take things for granted. I'd like to say it will teach me to not wait until the last minute to do things as well, but I'm an inveterate procrastinator. I'll just wait and learn that lesson another day.
