My sister's (Siberian Forest Cats) have conversations via my sis, nephew and me in Russian accents. My half-Burmese, and very forgiving cat, puts up with being aero-planed by all, and spoken to in a vaguely Chinese accent.
We sing all the time. If it's a bit cold, it's referred to completely unironically as a bit chillywillywoowah, accompanied by the 'I'm a bit cold' song.
At the arrival to the table of any home cooked dish, all my siblings (and the marry-in spouses have learned to join in) with a major chorus of ooooh-oooh! With various compliments on the look and smell of the dish.
On any given birthday, the birthday person expects when picking up the phone to be greeted with a sung 'Happy Birthday' which I have delivered in lifts/queues (though quietly). Birthday cards, no matter to whom, have the age with little flashes around it as the centrepiece of the written bit.
No-one is ever allowed in the bathroom (from tiniest babies upwards) in the bathroom, which is always locked, when someone else is in there. This springs from my DDad keeping his false teeth dark with four kids. My DH finds the inability to come and get his contact lenses when I am having a shower most annoying, but has learned to live with it. It's referred to as someone having their OPB (own personal business) to attend to.
My DDad used to work long shifts and so was referred to as PTOD (poor tired old Dad.. i.e. don't wake him up) which has now turned into PTO...x (insert acronym here. Which all four sibs still stick to.
Wine is greeted with further oohs and very exaggerated claims about vintage and origins, especially if it's a four quid supermarket home brand.
Are we wierd? Or are these just slightly eccentric family traditions?
