A good friend's mom is our florist. I don't know her all that well, have only met her maybe 4 times. Should I invite her since my friend, her daughter, will be attending? I'm a little apprehensive since I barely know her, but could possibly make room on the guest list for one more. BUT she has a boyfriend, who I've never met and my friend isn't fond of. Not sure if I have room for TWO more I barely/don't know. I don't want to offend my friend by not inviting her mom, who is so kind as to arrange our flowers (we are paying her, but i suspect she's cutting us a bit of a deal.) What do I do?
