I wonder whether Mike is getting annoyed with me. I had promised to help him 小题1: his maths in the library this afternoon. 小题2: just as I was about to start out, Uncle John, 小题3: had just come back from abroad, came to see me. John has always been a good friend as well 小题4: a good uncle. He used to come to see me when I was young, but I had not seen him for ages. 小题5: had a good chat and had a very nice time together. I tried to call Mike and tell him about the delay, but wasn’t able小题6: reach him since his mobile phone was powered off. When I got to the library, he was nowhere to be seen. He was likely to be very upset, since I should have met him there. I think I’d better apologize to him tomorrow 小题7: not keeping the appointment. I’d rather tell him the truth than make 小题8: excuse.
