Old people like to talk about their bowels. I am not sure why this is. I had an elderly lady talking to me about her bowel problems today. She then asked if I was coming home with her and looked very disappointed when I said I was working and couldn't leave. She's not the most "with it" but that doesn't explain why she went into full detail about her poo problems.
I'd like to say that this is an isolated instance, but this isn't the first old lady to tell me about their bodily functions of the hiney area. And I'm pretty sure it won't be the last.
