My parents are no longer alive. However, my Dad liked practical gifts that he would actually use. I would've preferred to treat him, but that wasn't what he wanted. Expensive aftershave/soap never left the box, jumpers went unworn, and he was never a drinker.
His favourite gift from me, was individual puddings from Georgie Porgie puddings. He liked that they kept for a while, didn't need to be refrigerated, and that I could make a custom order for him (he didn't like the flavours with alcohol in, except for cider/Christmas pud).
Speaking of the Christmas puddings, they are a firm family favourite. I've suggested making our own, but the kids say "No, it has to be Georgie's with Roddas". This sounds like an ad, but I assure you it's not.
Dad also liked that if he went to certain events, George the owner, would be there. The business originally started with the support of the Princes Trust, and he liked to think he was making a small contribution to helping another small business.
