what do you do? or What do you do for livin...?
One off my best answers is: - ''i have a good biznis on the internet.''
and when someone ask me what is it? i just answer: ''It would realy take hours to explane it, becouse it is very very complicated!''
And the good thing is i don't lie, and it is the best answer for me and for others. isn't it?
And when a girl for example relly have time to listen even fev hours,.. i just start to tallk some stuff that she don't undarstand... and ask her: ''do you understand something off that?'' .. ''u see, i told u it is to complicated.''
