When I was at school, I spent two summers at my grandfather’s. They were the (20) holidays I’ve ever had. Grandpa lived alone in a country cottage near a small river. Grandpa’s hobby was making birdhouses. He always said that he (21) a hobby to fill his free time. Grandpa’s workshop was full of all kinds of tools. There (22) a big table, hammers, nails, paints, and what not. And all the tools (23) carefully in their places. That was Grandpa’s number one rule. The (24) rule was, “Never buy a new tool if the old one still works.” In the workshop, when he (25) the birdhouses, I asked him lots of questions about birds. He (26) a lot about them! He could tell one bird from another by their songs and footprints. I was surprised that Grandpa (27) the birdhouses in bright colours. He explained to (28) that birds prefer natural colours that make their houses more difficult to notice and, for that reason, safer.
