This may be a silly question, but I started to wonder when I received cards from family and friends with only the female attendee. I.e. my mother-in-law signed her card with only her name - not her and my future-father-in-law. Some people addressed cards/gifts to only me, or me and my fiance. Regardless, I started to wonder what's the proper way to sign a thank you card? With my name alone, or myself and my fiance?
Thanks!
