Can I take materials from a construction site on the way home?
That does not sound good. Are you trying to get into trouble?
No, I'll sell them quickly to make a profit.
Those do not belong to you though! You should not take things that do not belong to you.
I'll be careful, I'll make a good profit, and then I'll upgrade my PC.
Is there some other way that you can save up money? They have security cameras in those places and you will be caught taking things that are not yours and you can be arrested.
