You feed Appa

Vaibhav said, I am 3 years old and so I am a big boy. So, I replied, "Well!! you don't eat by yourself yet. big people eat by themselves. I eat by myself, aunty eats by herself, appa eats by himself.". Immediatly, Karthik pitched in and said "Appa, doesn't eat by hemself". I asked him, "If so, then who feeds him". Instantly, without a thought he replied "You feed him".  Maids started laughing. I was struck and embarssed. I asked him when has he seen me feeding his father. For which he replied, that I had fed him Grapes. Then I remembered I had fed mangoes (not grapes) to all the three men of my life about a day ago. He was narrating that.
