I’m sorry I (arrived) so late, but I couldn’t (come) any earlier. I (received) a faxed message from Washington just as I was (preparing) to leave, and I had to (send) a reply at once. I tried to (put) a call through, but I (became) tired of waiting and finally (sent) a fax. Before I could (escape) (from) the office, I (received) a call from my sister. She had just (heard) that our father had (been) hurt in an automobile accident. When I finally (reached) the garage, I found I had forgotten to (buy) gas, so I had to (take) a taxi. It’s a wonder I (arrived) here at all.
