This is 100% the most stupidest thing she's done. I mean, it tops those shite pumpkin laundry yokes she made a couple of years ago and the test tubes with plastic flowers glued to her wall in the conservatory.
She's destroyed those tiles, that will not come off, at least not easily and without damage and discolouration to the tiles. Why would you not even put a plastic bin bag down first!!? Thick as tit, honestly.
What a waste of a perfectly good kids ball, donate to charity if you have too many, don't spray paint them and make them into awful looking oversized decorations. The smell will linger on them for weeks, just what you want in you living room, paint fumes.
This has to be an almighty troll right?? She can't be serious??
