I remember Mallapally and Appachen lived there for many years by himself after Ammamma, my grandmother died.  He had, as I remember, 3 Pappis to look after him, or rather Appachen and named them so.  One used to drive his car, one used to look after the whole area and I don't know what the other one did. 
Appachen used to do carpentry and had a set up in the back of the house for that.  I also remember that there was a TT table there and table with an inlaid chess board.  I remember going there once, when Kochu was very small.  So Georgie and I got to sleep with Appachen and he used to tell us stories till we fell asleep.  I think it was at that time he made a small tree house for us on a guava tree in the front of the house.
I remember there was a stream at the bottom of the back yard, which was clean and full of flowing water.  We have gone down there and caught small fish in a cloth and had baths there. 
I remember going out in Mallapally with Appachen and I remember a Malayalam song he taught me about the moon. 
I remember too coming to Kottayam from Mallapally once. 
I went back to see the house once after I was married.  I didn't go inside, but just saw it from outside.  Now it has been completely rebuilt.
