I opened up my host sister's english textbook to a random page and was very entertained. Here are some examples of dialogues:
-Hi, Dick! What a surprise! Your hair doesn't smell.
-I haven't been smoking since last year. I feel much better now
-Nick, You really look better now.
-I have been taking Coldrex for 2 days. I feel better.
-Hello, Mary! You look so slim!
-I have been eating only low-fat food for 5 months
Hope you enjoyed as much as I did.
