I have just seen an advert on TV for an anti-wrinkle cream (the one in the picture), which they described as "the perfect Christmas gift".
So let me make a quick announcement: If you buy me anti-wrinkle cream for Christmas I will be offended.
Just as if you had bought me a book called "Reiki For Controlling Bad Breath" or "How To Overcome Binge Eating Through Feng Shui". Not that I think there is any shame in having wrinkles or bad breath or an eating disorder - but if you are giving me something to help me resolve that problem then you are (a) telling me I have a problem which I might not be aware of or comfortable sharing (or actually a problem I might not have!) and (b) implying that you know better than I do how to address that problem. That will not fill me with festive cheer.
And if anyone does get you anti-wrinkle products for Christmas I recommend a little trick my sister came up with when someone tried to pull that stunt on us a few years back: look surprised, delighted, but a little embarrassed and hold it up while loudly saying "Oh gosh, for my bum! How did you know? Thank you!".
The one we were bought was one that claimed to fight "the seven signs of aging" which led to a four-day debate on what these signs were...
"Wearing cardigans is definitely one."
"I think buying Peter Gabriel albums might be one"
"Knowing the words to ABBA songs...?"
"Making a noise when you stand up?"
"Inability to use predictive text?"
Etc, etc. Feel free to add your own comedy signs of aging in comments if you know one!
