Walkin' on the Sunny Side of the Street

So my kitchen sink and dishwasher are backing up into my shower and overflowing onto the floor...ACK!! Looking for a 'sunny side' of such a thing can be trying...however...I ask myself 'what will getting my panties in a bunch do about it?'....then I breathe....and sop up the water with the dogs towels....try plunging the sinks....to no avail....currently I'm waiting for the water to drain below the shower door at which time I will attempt plunging in the shower....oh the joys of home ownership.....even with these little molehills that need not be made into mountains...I continue to love every minute of it.
