disappointed by him & disappointed with him

如果講 disappointed by him ，咁當事人只係衰一次，
但係講 disappointed with him，當事人就衰到貼地，返唔到轉頭。
所以，可以話
disappointed by him 係對事，係對佢衰左的一件事，仲有得救，
disappointed with him 係對人，係對佢成個人，冇得救。

我估你知道 disappointed 係失望的意思，所以上面我講，係講有幾失望。

disappointed by him 係 由他失望

disappointed with him 係 對他失望
