Henry (live) in a small village. He (help) the villagers collect letters at the post office in town.
One day, he (go) to the post office and (find) on the shelf a big parcel for old Mrs Tam. Henry (think) that it (be) too heavy for Mrs Tam to collect it for herself. Therefore, he (put) the big parcel on his bicycle and (ride) back home. The next day, when he (knock) on Mrs Tam's door, a big fierce dog (run) out from the back of the house and (try) to attack him. It (tear) his trousers. Henry was afraid and (climb) up a tree. A minute later, Mrs Tam (come) out from the house. She (say) loudly to Henry, ' Are you blind? I (put) up a sign here for two days!'
' (not worry), Mrs Tam. This (not happen) again,' (reply) Henry.
Since then Mrs Tam (not receive) any letters from her friends. Henry never (get) letters for her again.
