Persians look grumpy??? They don't!! Well, o.k. They do sometimes (as do I. Well, I mostly always look grumpy - but that's another story!)
Yes, from time to time we all get our pictures taken and the results don't show us as 'bright and happy' as we might be. I just had mine taken for my drivers license again and I look as if I (a) slept poorly to not at all the night before, (b) have awoken with a terrible case of indigestion, (c) have already had annoying run-ins with half the Universe, and (d) am ready to kill the next being who even attempts to come near me! But, oh hey - that IS how I normally am in the mornings. Oh well........ My point being.........
Have had a couple of Persians and Himalayans (all rescue babies) as well as crosses thereof. They CAN look grumpy and out of sorts. But they can also look.... well, manic (Grendel... gorgeous black boy. Tended to sit with half his tongue hanging out....); completely happy (Pip... well Pipkin, but called Pip) hanging half upside down from the chair, for no apparent reason except that it made him happy); happy and content beyond words (Medb, when curled on my Mum's lap); forlorn, (my lovely Muff (Mufflet) when tucked inside my steamer trunk hoping to go unnoticed so she could be packed along with my stuff and so accompany me off to wherever it was I disappeared to for months (University - it was a long time ago); and so on until now with my incredibly loved Winston - regal. He knows he is King!
But, yes, I suspect there is no one who can do 'grumpy' quite like a Persian. Unless it is me in one of my drivers license photos!
