I pulled up to Costco one time and there was an older woman in front of me. She was having a really hard time getting things to work. I was getting really frustrated with her and told my wife why is she here if she can't work the pump? Then I thought that could be my mom! I got out and asked if I could help her. She looked at me and said "could you, I would really appreciate it". Suddenly I wasn't in such a big hurry. Turns out she was from Willcox and we knew a lot of the same people. Mostly I am an [bleep] but sometimes I'm not!
That is something everyone should think about, including myself.
