I'm not religious and love Halloween. I have always celebrated it and my dp celebrates with me. Nothing too scary or out there because our kids are young. No chainsaw Massacre figures in garden or dripping blood, just the usual pumpkins, ghosts and witches, food and pre agreed trick or treating with neighbours. Our kids love it too for dressing up and have been taught in a fun way and not a 'celebrating evil' way.
Anyway, sil and mil invited themselves down this week. I didn't invite them and made it very clear to dp that as it was half term I would be doing the usual Halloween stuff so kids don't miss out. Dp fine with this and we arranged a few activities like pumpkin picking, carving etc. Sil and mil here the whole week. Both kids going to the village party but no expectation for either mil or sil and kids to attend, just one evening.
Anyway, sil been fine. A few questions about it, nothing phased rudely. Politely declined Halloween party, which we offered with the caveat if it's not her thing that is fine no judgement. Sil is a fairweather Christian, eg church for marriage and getting into schools so we weren't sure if we should ask or not but thought it would be rude not to.
Mil has been making a few snide comments. Kids watching ridiculously sanitised Halloween songs on TV (think cocomelon) and scoffs things like 'how can they have a 'happy halloween' with all those ghoulish characters? Trying to dissuade kids from their own pumpkin designs and do ones she approves of etc. It's all been very low key so I haven't mentioned it to dp but aibu to think that as she knows we have conflicting views and she invited herself down knowing full well we celebrate it she needs to keep her views to herself? It's starting to grate on me as I don't want my kids to start seeing evil in perfectly innocent dressing up etc.
I feel it's a bit like if we invited ourselves down at Christmas and then made snide comments about going to church.
Aibu or is sil approach better and mil is engaging in weird power games?
