I'm watering my yard front and back

And my neighbor accross the street is yelling really loud inside his house. I know he is not yelling at me, but I hate to hear it anyway.

I only could hear him when I was out turning on the water, so at least he is not so loud that I hear him inside my house.

He didn't look like someone who would yell - he has a ponytail, shouln't he be like a kind flower child type person? I hope he gets a grip.
