****說謊的人****

若然你同情佢係為咗保護自己而講大話嘅話，咁咪仲當佢係朋友，同學，親人咁對代囉。

但如果你覺得佢咁嘅行為又損人不利己又黑人憎到貼哋嘅話，咪決絕啲唔好當佢係人咁對代囉。

雖然係好絕，但係要憎恨一個人就要做得絕啲嘞。



希望可以解答到您嘅問題，同時請原諒我教你做到咁絕情sorry sorry，但對呢種人冇辦法唔係咁做。Thanks.

i just leave him alone and not getting any relations to him

朋友, 同學- get another friend, this friend is not reliable 親人- try to tell him/her that this is not the right thing to do and help him/her to quit this habit
