What quality of your spouse do you least like?

He is so unpredictable. You couldn't tell what will happen next. Sometimes he is so happy, and with just a blink of an eye, he'd turn into a monster. He gets irritated with simple things, not just within the household, but also when we are out. He easily gets furious and you'd always hear him say a lot of things and sometimes I'd see him talking to himself already out of anger.
