I  swapped my neighbor's patio furniture
Why did you swap their patio furniture?
I did it out of boredom, it was indeed a very boring time for me.
I hope you replaced all their furniture, as it's wrong to steal from others. It's also important to maintain good relationships with your neighbors, so making them angry by stealing their property is not the best idea.
Whoa, I don't care about my neighbors. I just did it because I was bored.
There is no justification for your stealing. Find a hobby or something to avoid getting bored. It wasn't your furniture so you should apologize and replace their furniture.
