Correct responses, if you enjoy uninvited visits from Dani especially of the over night sleep over variety are:
Yes, Dani, you are right. Yes, yes, yes you are so right. Also multiple - I am so sorry, please forgive me, for I know not what I did, but for that I am so very sorry, and I will never ever never do it again I swear to Oprah who art in heaven.
WHATEVER you do, avoid the use of the words "towel" or "blue Loctite" for at least a year. Or 3. Or until a week after you are dead.
Forever is better. Do not expect Dani to forget. She won't. 10 years from now, tomorrow, next week, 3 months after Armageddon. The blue crap on the towels she gave you will be The Worst.
Variations of the above are ok, but DO NOT use the word "towel" in a sentence or a request or verbalize it in any way. BTW - your shop towels are now shop rags. Your bathroom towels are now Multi Looped Woven Fabric Drying Devices.
Or.......
Take the other track. Grunt like Tim Allen and make monkey noises and scratch yourself where the sun don't shine, rip a fart and say stuff like, Towels are grease rags, who cares, I don't GAS. What the hell is your problem with some crap on some stupid towels anyway? Not that I suggest this method, because of the thrown objects & trips to the ER. Also, the screaming makes my ears hurt & it's hard to listen to George Jones songs over the racket.
Your Bed, Bath, & Boredom idea is a good one. Purchase the correct amount of MLWFDDs & display them, after running them in your washing machine, to "prove" you got the Horrible Blue Stains out. Practice looking like Opie Taylor when Aunt Bee catches him with his hand in the cookie jar. Also, candy, flowers, wine (extra wine - good), and things that sparkle in the sun that cost 1/2 of a gobzillion $$s - but not as much as your extended saddle bags that look very good BTW.
Good luck. Actually I have no idea. None. Not a clue. Nobody else does either. No one understands wimmens. No one. Especially the poor sad men who think they understand wimmens. Some think wimmens who like dogs can be distaracted by said dogs to the point they will temporarily forget why they did whatever they did that to men seems irrational, but it is only semi reliable. Try to keep a dog (s) close by to see if this method works. If it does, rinse & repeat. Or run like hell, all wimmens are crazy. Either way. HellifIknow.
