He missed his dinner but enjoyed his supper

Supper was already over when a guest unexpectedly arrived.

- Would you care for some macaroni and a piece of an apple pie? - mother asked.

- Thanks, it comes just at the moment, I missed my dinner being on the way and am rather hungry, - the guest answered.

Mother put another plate on the table for him and brought a dish of nicely browned macaroni from kitchen.

- Keep our friend company, Jackie, while I heat the apple pie and coffee, - she said.

Jackie ran out of the room for a minute and returned with a neatly cut piece of cheese on a plate.

- There's a good boy, - the guest said having finished the macaroni and the cheese. - A clever boy always knows what may be found in the frig.

That didn't come from the frig, - Jackie answered triumphantly, - it came from the mouse trap.

THEY CAME TO SEE ME OFF

The porter saw three men who arrived at the railway station at about half past nine in the evening. One of them came up to the porter and wondered at what time the next train was to start for London. The porter told the man that the trains for London went every hour.

The three men decided to go and have a drink. They came to the refreshment room and ordered three drinks. A minute or two after ten o'clock they approached the porter and asked him if the 10 o'clock train had gone. The answer was affirmative. Besides the porter added that the next train was due to start at 11 sharp.

The three men returned to the refreshment room for another drink. They missed the 11 o'clock train in the same way. The porter had to warn them that the next train was the last. If they missed it they would have to spend the night at the railway station.

Twelve o'clock carne and the bat train was just starting out when the three men came out of the refreshment room, running as hard as they could. Two of them managed to get into the carriage just when the train was starting off.
The third man could not run so fast and the train went on leaving him behind. The man stood at the platform watching the train disappear in the distance. The porter who saw all that was very sorry for the man. When he came up to the man, he saw him laughing. The porter could not understand why the man was laughing. Pie wanted to ask him a question, but at that moment the man said to the porter: "Did you see those two boys get on the train and leave me behind?" "Yes, I saw them", answered the porter. "They came to see me off (Они пришли проводить меня)", explained the man to the porter.
