Agghhhh! Anyone else have a family that makes them do that?

So had a pretty good day out with my son and wife and then it all goes pair shaped. We're playing a game on the bed and she spends most of the time complaining she's not feeling too good, she ate something or drank too much, or something hurts or something...she's always complaining about some pain or ache or something and then when I'm just about fed up of that I catch him picking his nose and eating a booger....so I go off on him and leave the room. I'm just tired of family shit sometimes. There's always something.
