My family are just... difficult. They disapprove of alcohol, and live a ridiculously healthy lifestyle which doesn't include biscuits or sweets or any kind of 'junk' food. My sister's kids are not allowed that type of food either.
They are also extremely fashion-conscious, so wouldn't wear a souvenir t-shirt or hat, and they are antique dealers who use their home as their showcase (people make appointments to come and view items in their home), so they wouldn't really welcome souvenir-type things that wouldn't fit in with their decor.
In the past, I have given the kids CDs and been told to take them back, as they only listen to Christian rock. And I've brought various food things, which were rejected. (Mom actually threw the Rafi's curry spice packs in the bin, because 'they stank'.) They did like lemon curd at the time, but I think now that would have too much sugar for their tastes/health concerns.
However, I loved the idea of magazines (home interiors, antiques, Period Home, etc)... I've done that in the past and they loved them. Tea towels would be good as well.
I think now I am just thinking about what to bring back for the kids... a sporty 11-year old boy (I've previously given him a Scotland football top, which he didn't seem all that interested in), and a 15-year old girl who is an actress and singer in local and school drama clubs.
And on the other hand, I am (somewhat bitterly, perhaps?)thinking... why do i feel the need to take presents at all? I am the one who is laying out all the money to come visit..., I am the one who has a lot of financial stress after losing my job a couple of years ago and having to take a low-paying job just to stay afloat. They are the ones who have *everything*, so... do I even need to be thinking about this stuff?
