We've received an invitation from a bloke my DH has been friends with for 10+ years. They're not close but studied for professional exams together and a small group of them are still friends and get together occasionally. I have known him through DH for the same amount of time.
I never noticed him get my name wrong when we meet but as its not often it may just not have registered (I'm a tiny bit precious about my name as its not common but is a variant of a more popular name).
Anyway the invitation has arrived with the wrong name aibu to think that if you were unsure of spelling etc you at the very least check Facebook or with mates or verbally with dh?
Not offended by the invitation or suddenly hating perfectly nice people so this is a tiny bit lighthearted
