u only feel bad if the person shouldnt be smokin weed like if theyr doin a important test the next day, or when you sell to like a 15 yr old, u cant help but think they shouldnt be usin a mind alterin substance whilst there brain is still formin, or when you keep sellin to someone and you notice that over time its changed them in a bad way, or when you sell to really heavy smokers and wonder if you wernt sellin to them they would be doin more wit there life, the biggest thing is you have to run around all day deliverin weed to people, you get really tired, the paronoia when ur carryin big bits often is what make people quit sellin. but theres a good side, for the people who it helps like old people or this 1 guy i sell to wit m.s it reaaly helps them, it gives you a perspective into how good weed can be, and how bad it can be, i see it doing more good than bad, and at the end of the day its just another job that has to be done by someone.
