What a cool grandpa.
Somehow it heals me a little to see him like this. When you get older, there's a lot of things you outright can't do because of your own health and the health of those close to you, but... In some cases, there's just a lack of drive to try to make things possible. Like, you don't want to have to learn new things, or you don't want to have to rely on others. So seeing Jii-san still have that drive to go to great lengths to express his love for his wife is what heals me.
