Panel 1: As Elly puts her dress back in the closet, she reminds herself that there's nothing like being away to make you appreciate being home.
Panel 2: She does the Stupid Hoop-Yah Dance when she lists the wonderful things about being home: she can sleep in her own bed, she can make coffee when she feels like making it and she can raid the fridge. Yes, being home is a wonderful feeling.
Panel 3: The wonderfulness ends when we're reminded who is also home: her assbucket of a son who threatens Liz with mayhem because he insists that she is wearing 'his' shirt when it's probably hers.
Panel 4: As she saunters down to break up another pointless fight sparked by the fact that Mike is a worthless piece of shit who hates the idea of sharing, she grumbles that it's too bad it doesn't last longer.
Summary: If Elly wanted peace in her house, she would do very well to; destroy the Looming Shape Of Imbecile Malice that haunts Liz's subconscious mind. Mike should be told to throttle down or get throttled because Liz didn't ask to get born either even if he does have to share crap.
