There's a certain amount of freedom involved in cycling: you're self-propelled and decide exactly where to go. If you see something that catches your eye to the left you can veer off there which isn't so easy in a car and you can't cover as much ground walking.
It's not a struggle but sometimes when you're gone for a month or two you start to miss your friends. I love acting so much that it fills that gap of being sad about not being able to see my friends.
