a friend in need is a friend indeed, (需要幫助時伸出援手的朋友才是真正的朋友。)患難見真情。
lend your money and lose your friend. 不要把錢借給朋友，如果借了，要么你朋友會因為你催還錢而不高興，要么你會因為你朋友不還錢而不高興。
you should not lend money to your friends; if you do, either you will have to bother your friend to repay the loan, which will make your friend resent you, or your friend will not repay the loan, which will make you resent your friend。(這個不太符合中國人的觀點吧…不過也有它的道理的)
short reckonings make long friends.好借好還再借不難。怎么外國人的朋友的名言佳句都是借來借去…
with friends like that, who needs enemies?說的是如果有這種人做朋友，還用得著敵人嗎?說這朋友很不夠義氣。

when a friend asks, there is no tomorrow. 朋友的要求不要拖。
