There's a lot of it about they say.
Do you borrow Mr Wench's man sized hankies or treat yourself to those Kleenex with the Aloe Vera in them?
When I was a kid half the class was walking round with Vaseline smeared across their top lips (Alright Darwin, Berek et al you know what I mean
) at this time of the year. Don't see that anymore but my children still all get colds during this half term leading up to Christmas and sniff all day long with the resultant red upper lip and soreness.
We used to have Vick rubbed on our chests... 
That too. Pity the poor teachers who must have found the collective sniffing and stench of Vick hard to put up with. No wonder they dashed for the staffroom and a drag on a cigarette at breaks. Mind we had some who used to smoke in the classroom as they taught.
One, who taught art, used a cigarette holder and wore yellow socks ~ we were very suspicious of him.

Another, an ex army man, smoked a pipe. Used to get one of the boys to nip out for an ounce of shag from time to time.
