In-laws want to do secret Santa for Xmas this year, a message was sent round the group chat that I am not in but have been asked about that asked if everyone was up for doing secret Santa this year so one person buys for one person from everyone if that makes sense, now I'm wondering whether I'm being unreasonable because to be honest we don't really know the in-laws it's only partners mum that we see, we haven't seen or spoken to his brothers and their partners for over a year, they never bother with our dc send a bday present etc but don't see her, their the type to drive past and not bother despite being invited etc I wouldn't have a clue what to buy them either, Wwyd in this situation ?
