We are much happier in our new house because it has a large garden, and you know how enthusiastic we both are about gardening. When we moved in a month ago, Mary wanted to get a dog to keep out burglars. However, we finally decided that it would be cheaper to put an iron grille in front of the door and get a burglar alarm.

Last week, I went to a shop and bought an alarm for just over £200. It consists of a control unit with three smaller units. I put the control unit in the lounge and put the other units in place by the front door, back door and lounge windows.

That night I soon fell asleep because I was confident that no one could get into our house undetected. At about 1:50 a.m. I woke up suddenly and heard the siren. It was like an ambulance driving right through our bedroom. I couldn’t leave the siren on all night. I went downstairs in the dark. When I reached the bottom of the stairs, I switched on the light and looked around. Oh my gosh. The back door was unlocked. I rushed to lock it and it was just at that exact moment that the ‘burglar’ disappeared behind a curtain. Guess what? It was an ordinary house lizard(蜥蜴).Apparently the alarm system had been made for American or European homes in which lizards are never seen. I switched the alarm off and sat down to watch. A few moments later, a lizard ran across a wall, right in front of one of the alarm units.

I won’t bother to finish this story but if you’d like a burglar alarm system free of charge, just let us know.
