Frequently Asked Questions
What's a good birthday message for a grandfather?
Something specific about what he's meant to you — a memory, a quality, a lesson — lands better than a generic wish.
What if my grandfather lives far away?
A phone call paired with a written message often means more than a text alone when distance is involved.
Is it okay to joke in a grandpa's birthday message?
