Every time she comes round she looks always has a 
face.
Well, let me tell you about some of her quirky ways:
She's just constantly washing her hands, between every household task. What a way to waste soap. tut.
She won't iron my PFB's underwear, when she knows he likes a crease in his socks. (I've reminded her enough several times.)
She embraces the modern throw-away culture. I can't see that she doesn't understand that those two broken microwaves might come in handy one day.
She's such a food snob - Potato Pie has served me well over the years at many a dinner party, but she gets very sniffy about it.
She doesn't have a WarCupboard 
who knows what would happen if the shops ran out of vital supplies. Oh yes - she'd soon be round for Shredded Wheat, baked beans and loo roll then wouldn't she?
She washes tea towels - they're fine with just a quick dry on the radiator and a shake, surely?
And, don't get me started on the wanton beverage consumption. Coffee at 11 am? . 11.30 am's fine though, of course.
They wouldn't even consider letting a pet in the kitchen, nice bit of company for me, Tiddles is, when I'm chopping vegetables.
On the subject of veggies - what's this new-fangled frippery about under-cooking veg - when DH and I eat a roasts at DIL's, we might as well have had raw veg with the meal, the amount of cooking time she gives them. 
She calls my PFB by his first name. Everyone knows that once the children has arrived it's imperative to address him as Daddy.
She will not accept that a working knowledge of bowel movement is the key to a healthy life.
I just wonder if anyone else had peculiar DILs?
