My mother in law before she passed away use to send me greeting cards and suddenly she would send them unsigned but the ones she would send my husband she'd sign. I kept it to myself but something about it didn't feel right, we weren't very close, i don't know if that was her way of letting me know how she really felt about me. Now a dear friend who haven't spoken to in a long time sent me a birthday card unsigned. am i making a big deal out of nothing or not signing these cards a statement.
