Making people feel appreciated

My project is I am going to be sending my mamaw and papaw a nana and people like that cards so they can read them and know that I am thinking about them.I think that is a good idea because I am sure it is pretty boring so I am thinking for them to get a card in the mail would be exciting.I think they will love writing letters back because who doesn't love getting letters.My goal is to cheer them up and give them something to look forward to when I send them letters every weekend.I am sure they feel kind’ve lonely so I want to make them feel appreciated.
