Or than again maybe Kati would go birdwatching with Tong. Mostly they watched waterbirds or birds that lived on the edges of the fields. Tong carried his sketchbook everywhere, and when he saw a bird he'd sketch it and then compare it later with a reference book to find out what bird it was. Grandpa encouraged him in this, frequently getting him bird books from overseas. Everyone in the house counted Tong as a member of the ้household and Kati often susoected that, as well as helping out with the chores, Tong must have done some great favour for Grandma and Grandpa in the past.
