Why is it easier for me to drop inside out or straight on as opposed to across my body?

For example, I’m playing on the left side, I set up for a forehand drop shot, and 9 times out 10 it feels easier to hit that shot to the opposing left side player.

Another example: If I’m playing on the right and I’m setting up to hit a forehand drop shot, I’m almost never going to the opposing right side player.

For backhand drops I’ll go either inside out or straight on, but never across the body.
