Things can become complicated with resistance.
It's one thing to watch a child perform a move during class, but the dynamic changes when a resisting partner/opponent is added. For the reasons Tyler and Scott mentioned plus there is a good chance that the other person knows what you are doing. These all just keep adding layers, but this is where jiu jitsu helps kids and adults become great problem solvers.

I don't think it is hard. Actually I think it is easier. Gary Pond is right, you really know that person. I think some of my best training has come from when I have a friendship off the mats. These are the people who have a vested interest in you becoming better.
Additionally, these are the people who know and understand why you are going hard or pushing more. They know your intention vs someone else who might take it as being overly aggressive or mean.
If nothing else communication is key. If you don't know someone well saying hey I really want to push today, today was a bad day I need a hard roll, I really want to work something or I'm prepping for a comp can go a long way.
