can a man be trusted?why or why not?

Of course a man can be trusted. There are some (many) untrustworthy people of all ages and genders in the world, but that doesn't mean that anyone should generalise and deem every person in that group untrustworthy. That's just as ludicrous as racism. People have breached my trust in the past, and although it can be hard to recover from that betrayal - of a friend, loved one, relative etc - we can't refuse to trust ever again. I learnt that we can't punish others for the mistakes and actions of people from our past. =D

i think some of them not all

It depends on the man.If he hasn't lied to me, I'll trust him.But after I catch him in a lie, except the kind you tell to keep a gift a surprise, I never trust him again. I will assume that Everything he tells me from then on is a lie.
