half case

A few days ago, a friend and I went out to dinner, at dinner, they say, is to drink, but I this drink is not very good, so I have been asked, each time a drink, drink only half case, because I am afraid that he’ll put a cup of wine to drink all the his words, can’t stand it, so I just drink a cup every half case, so drink up is better, friends all know me, and therefore I drink a cup of half case, they also have no what opinion, because the good of our relationship, whether I drink drink less, they are not mind.
