With you there - when else is it acceptable to have a nip of sherry before lunch, and be pleasant to complete strangers inside central London? :o) I actually think Christmas is the one time of year people behave like normal humans, and the only reason they overdo it on the booze is the sheer relief that comes from not having to be a hatchet-faced generator of tax-revenues. It's also the only time many people are actually able to prioritise family, friends and the fun bits of life, like giving gifts and sharing food, instead of bolting down a sarnie at their desk, and working unpaid overtime. So I find all the grouchiness amusing, but don't expect me to join in! :o)
