it will be very fun to play some nice old song (theresa theng's song normally they will like it very much) with an accoustic guitar and sing along for the old folks in old folks home.Can chit chat with them. felt pity with those old ppl where their family abandon them. also can buy them some goods when u go along . for example now u can buy mooncake for them if they are chinese. Go with a gang of friend to cheer them up and bring some warm to them,
