Wait until you jungle. Many feel they're entitled to kill your jungle creeps and take your buffs whenever they please without even as much as asking.
At least most people don't bitch when you farm their lane after lane phase so you kinda get used to it after a while, but I've seen people who wouldn't even let me (the jungle) push a lane after the lane phase because that was supposedly their farm, and they typed that whilst busy clearing my shit; now those are the worst.
......
Mid lane can be quite bad too, I guess. After some point in a match, most people would come and farm at mid, especially in lower elo where most players focus playing around mid-lane and only really push the side lanes when there's nothing else to do.
So if you play champs who have bad clears in mid, you gotta prepare yourself, because your cs/min typically fall off a cliff once everybody gathers around the mid lane.
