There are certain expressions which must have come about for a reason.
Take 'let sleeping dogs lie' for example. This was perhaps wise advice passed down the generations by the first person who surprised a snoozing canine and had their leg savaged.
I think this expression should be extended - 'let sleeping people lie' is also good advice. Unless of course you think they might be dead, and then it's quite acceptable to get a small mirror and hold it under their nose to see if it mists up. Be warned though, should they suddenly awaken they'll wonder why they can see up their own nostrils and may of course die of fright. Please don't blame me if this occurs.
I'd like to add 'let sleeping cats lie' as something to pass on, or at least my husband would.
Let me explain - a little while ago my daughter found a pretty cat on our compost heap, sleeping in the sun. My husband - aka Dr Doolittle - decided he would go over to talk to it and stroke it.
It purred gently, butted its head against his hand requiring more fuss, and then when husband removed his hand to walk away, the cat leapt up, sunk its teeth into said hand and badly scratched both of his arms.
I remained blissfully unaware until husband appeared in the kitchen with blood dripping from both arms like an extra from a horror film, closely followed by daughter who looked shocked as she'd witnessed the cat attack.
After a quick call to 111 - I'd read you should seek medical advice after an animal bite - we headed to Corby's Urgent Care Centre where he was given a week's course of antibiotics (thanks for the great care he received, it's a fantastic facility and long may it continue).
While we appreciate that not all cats will behave like this, please take our advice and let sleeping cats, dogs and people lie!
NB - the cat was unaffected by this incident and still visits us; on the last occasion it strutted past the kitchen window with a pigeon in its mouth.
