Dude, you're also a pig

Look, I think it's great that you, a busy man in his 50's, would take the time out of your day to bring your mom to her appointment.

And I don't mind (too much) that you farted, loudly, in my office. I'd rather you have done it elsewhere, but sometimes we can't help it.

But, in all honesty, you then smiling and saying "Boy, that felt good!" wasn't needed. At all. I am not one of your beer buddies, and we are not in your living room.
