A note for the house sitter
Hi Sam! Thanks for looking after our house this week. Here are a few things you should know. You can sleep in the guest room, and you can eat anything in the fridge. You don't have to water the plants, because Mrs. Lee from next door does that. But you have to walk our dog, Bella, twice a day, and you must not give her chocolate. It could make her very sick. The back door is old, so you might need to push it hard. Mrs. Lee may stop by on Thursday. Could you give her the yellow envelope on the table? Oh, and Bella can open the kitchen door with her nose, so you must keep it locked! Call us if you can't find anything.
