I have a good friend - we don't live close to each other, so Skype and text as much as we can.
Recently, she has started sending birthday/Christmas/anniversary/etc cards signed "Friend's DH, friend, DC1 and DC2". Bearing in mind I've met her husband 3 times in 9 years and don't particularly like him I find this a little odd.
When I send cards to my friends, they're really from me to them. I put DH and DS's names on there after mine as it's polite, but my DH doesn't even know they're being sent, and I can't imagine that my friend's DH knows either. It's all in her handwriting, too.
AIBU to think that by putting her DH's name first, she's behaving as though she thinks he's more important than her?
