I think it was good one to make your girlfriend feel alright but since she didn't notify your of her coming, it was a bad one has she altered your arrangements for the day and led you to ditching your friends for her which wouldn't tell well of you. Anyways, it was good you were still able to see the football game and have a little fun. Concerning your friends just find a way to make them not so dissappointed at you for your failure to meet up as planned.
