So, do i buy a present for SIL's boyfriend or not?

[santasaltire]

She is only 19, and has just bought a house with this guy. DH and i have only met him once, although she has been going out with him since she was 17. The time we met hiom he sat with his face down staring at the floor for an hour, ignoring us chatting to him.
"He's very shy" Is what we were told.
DH thinks we should buy him something, to keep things tickety boo. I think we shouldn't.
Anyone care to add their views?
Should add that i already have SIL's present, bought a few months ago before she bought the house with him

I'd buy him something small, he's becoming part of the family. Two years together and a joint house purchase says this is serious relationship.

Perhaps buy something in addition to your sister's pres for them both,as a kind of housewarming present. Maybe he just needs time to get to know you all ? I'd be inclined to get something,to keep things sweet.

I don't buy for my sisters' husbands

TBH it's a bit of a sore point. Last year we were told that SIl was going to buy us presents from herself (the boyfriends name wasn't even added to the tag).
The DS got a £2.99 selection box each, and DH and i got a bottle of Lambrusco. now, i know it's the thought that counts, but i found out later that she had bought her cousin and her husband a beautiful Border Fine Arts model, and the cousins DDs a Barbie Princess something or other. Now i got annoyed this, because after all DH is her brother, and whilst i don't expect her to go out and buy us a BFA model, i expected her to get him something more than a £1.99 bottle of wine.
We have also had hints dropped by PIL and step MIL that SIL may not be buying presents as she has just bpought a house - yet we have two chidlren, 6 parents and step parents between us, three brothers, two SIL's and, a live in girlfriend and three neices and nephew to buy for, yet no one asks us if we can afford it.
So, i feel that the £10 i spent on SIl is enough and am really at a loss what to do about the BF

so get them a cheap box of chocs for the house. if they don't get you anything, say 'oh, good, we'll all do that next year' and don't.

only buy him something if you and them will be around the christmas tree at any point. then buy him a ice scraper for the car from M&S for £1.99

I wouldn't buy either of them anything. Waste of money, imo. You'll end up spending money you don't want to spend on a present they don't really want. Christmas nowadays is little more than an elaborate con to get us all to spend money needlessly. Don't fall for it.
Bah, humbug!
