My mother will sometimes buy things for me, mostly for Christmas and birthdays. If she spends quite a bit of money, eg £30+, she'll say she wasn't going to tell her husband she'd bought it for me and to keep any money she has spent on me quiet from him. I have no idea why as he wouldn't judge her buying me anything or even bat an eyelid. I've asked her not to say that in the past as it makes me feel like I'm not worthy of her husband knowing I get gifts or something. I honestly don't know the reason for it but it really gets to me. He even sends his adult son hundreds of pounds per month as he lives abroad and doesn't work but my mum has this weird thing about her husband must not know when she's spent anything on me. It is so odd!
