My MIL's DH used to be a big whisky drinker. He was a well known face in his village and popular and many people knew he liked Whisky.
So, over the years many people bought him Whisky.
What they didn;t realise is that over time the amount he actually drank was a LOT less than the amount he received, basically meaning that there was a LOT of bottles in the cupboard.
He died in February this year.
My DH received a bottle of whisky from his Mum for his Christmas - his main present from her - he does drink the odd whisky butt not a huge amount - probably about 1 bottle a year worth.
On putting it in the cupboard its obvious from writing on the box that it was one of the bottles gifted over the years to her DH (there is a message written on the bottle of "To XXX from YYYY and ZZZZ").
Sensible of his mother to get rid of some of the many bottles she is left with as presents (she doesn't drink) or mean of her to give an old bottle of whisky from someone else to her son?
