My husband works a crazy schedule of nights and days. Sometimes he is in a super great mood and we can all enjoy our time together. Other times he just wants to be completely left alone and will go hibernate in another room and is highly irritable if disturbed. Sometimes it's really ticks me off and upsets me because I want to spend time together and he can't get over himself enough to spend time with me (uh ok this is hormones talking right here).  Is this just how men are?
