Final answer:
The provided information lacks any context about Martin and his grandfather's gift, making it impossible to determine Martin's readiness to receive the gift.
Step-by-step explanation:
The information provided does not contain direct insights into whether Martin is ready to receive his grandfather's gift or not.
The extracts from various texts include reflections on moments of sharing, loss, nostalgia, and the importance of personal connections, but none specifically relate to a character named Martin and his readiness to accept a gift from his grandfather.
Without a context or a story explicitly involving Martin and his grandfather's gift, it is not possible to ascertain Martin's readiness.
