The three events in the narrative that develop the idea that the grandfather deserves the award are:
1. **The grandfather employed people from the town in order to "keep his community strong."** - This shows his commitment to supporting and strengthening his local community.
2. **The grandfather served as a volunteer firefighter for many years.** - This demonstrates his willingness to give back and serve others in a significant way, highlighting his dedication to community safety and service.
3. **The grandfather's hardware store became "the place for how-to advice on do-it-yourself projects."** - This reflects his role as a resource and support for residents, fostering a sense of community and encouraging homeowners to engage in improving their homes.
These events illustrate his contributions and impact on the community, which justify the award he received.
