Do not wear ratty old slippers with crooked floors and a pee pad right in front of you that the dog just used.
Do not wear ratty old slippers with crooked floors, used pee pads in the way, a dog always underfoot, and a vacuum cleaner in your hands.
More helpful advice:
When the ratty old slipper gets caught in the doorway and you slide across the pee pad on your backside, be sure to throw the vacuum across the room without hitting the dog and then twist yourself into a pretzel to avoid slamming into the 19th-century mahogany rocking chair.
I’ve learned my lesson. I will stop vacuuming on Sundays. 😇
