Living in the land of kids this is the best example of my week I could think of...
Wife: Our 19 year old boy is going to paint the 'kids' bathroom.
Me: That's great! I haven't had time to get to that one!
Wife: There is a little paint peeling around the shower head. Can you fix that first?
Me: Scrapes the peeling paint.
Me: Removed all of the caulk from around the tub surround.
Me: Finds that some of the drywall tape is peeling so I remove that too. Why in the world anyone would run a strip of drywall tape around the top of the tub surround is beyond me.
Me: Patches the area where the paint was peeling and all the way around the surround.
Me: Removes the towel bars, shower curtain rod, TP holder etc.
Me: Finds and fills all of the screw heads that have popped over the years.
Me: Removes toilet tank.
Me: Has to use a grinder on the toilet tank bolts because they are not budging.
Me: Wipes down all the walls.
Boy: Tapes and paints bathroom.
Me: Goes behind boy for touch ups.
Me: Cleans tub.
Me: Re-caulks tub.
Me: Buys new bolts for the toilet tank and re-installs.
Me: Installs the towel bars, shower curtain rod, TP holder etc
At work we'd call it project creep.
