He likes photography.
We've done pretty alright for Christmas gifts for them. I always follow "edible, potable, disposable" rules for gifts.
Last year we did a meal on a steam train.
The year before was a bird of prey photography experience.
This year is afternoon tea at a fancy hotel.
But just the FIL is tough. He rarely drinks. Is hard to please with food (to be fair my MIL is the best cook in the world). Would rather die than go to a show. <sigh>
Husband bought him a nice cheese platter from Harrods one year and that bombed. Grrrr.
I leave it to my husband. Last year he bought him a Nivea Men's gift set in the 50% off stuff after christmas.
But he's 70. Needs to be recognised.
