person A: My grandma sent me a birthday card in the mail! She is such a sweet lady.
person B: I wish I had a grandma.. did she send you anything extra?
person A: I can understand that. She is the only grandparent that I have left. She only sent a card_comma_ but she is living on a fixed income.
person B: That is still really sweet.  I never knew any of mine.  Treasure her while you can!
