Women seem to have a bad habit of lashing out at others when they're upset about something, especially when it's unrelated.
Stressed out at work? They lash out at the people closest to them.
Hungry? They lash out again.
Another interesting pattern I've noticed is that they very very rarely get mad or lash out at the people ACTUALLY responsible for them being upset. Almost like they're taking advantage of the fact that they know those people won't fight back, so they're free to be her lashing out targets.
