<human>: Summarize the given text in a few sentences.

Today my friend and I pitched in to buy something for a mutual friend of ours. She wanted to get it, but didn't have the money so me and my buddy got it for her. I gave him my half of the money and he gave it to her, but didn't mention that I pitched in. He didn't purposely omit that information and offered to tell her when he realized he forgot, but I figured who cares as long as she's happy it doesn't matter. Obviously I feel good for doing something nice for a friend, but part of me wants to be like George Costanza and take partial credit for my Big Salad.
