Monday, April 17

Dear Gramps,

I was so upset last week when somebody stole my Super Racer from the park by your house. I called up the toy company but they said they have only red, blue and green racers. Dad called Cobb’s Toy Store today and found out they might have purple ones. Can we go there when I come to visit you next week?You and I were only gone for a few minutes to the shop down the street to get ice-cream and cookies. Maybe the thief was watching us. Mum was surprised when I told her the racer was stolen. She said she used to leave things at the park all the time when she was young. Once she even left her bicycle for two days near the swimming pool.

Tell Grandma that I like the food she made last time. Ask Grandma if we can have pancakes with sugar for breakfast when I come this time. I have packed in my towel, comb and soap. Tell her this time I won’t forget to pack in my toothbrush.

Love

Toby
