OK - I know I will end up doing this as it's not really a biggy ... but wonder if I'm being unreasonable to feel a little bit 'told' 
Love in-laws by the way - so not an IL bashing thread.
In-laws have nice best friends. Quite involved with the family but very much more so with SIL's.
We receive Christmas cards from the friends and see them at the odd family do. MIL has said for me to bring one of the couples birthday cards with me next time I see her to save me a stamp.
No - it's so-and-so's birthday so would you like to send a card? etc ... just told to bring it with me as if it was a given.
We received an anniversary card from said couple last year and now I'm wondering if they were 'told' to send us one? I really hope not and that they did it off their own back.
I have extended family members that we just don't do cards with so if not told, I probably wouldn't have sent one.
Plus, why wasn't DH asked rather than me? (because he wouldn't have got round to it!) 
AIBU to want to have been given the option or am I being a teenager not wanting to be told what to do!
