Illegal Church
We have nothing against religion and as far as we’re concerned, everyone has a right to believe in whatever they choose to and practice however they want. Having said that, it’s absolutely not okay to illegally convert your garage into a church and then hold loud services in there every Sunday, all night long.
Did they not for a minute think about how they’re going to inconvenience others? The irony of it is that they seem to have totally forgotten the whole “Love thy neighbor” bit. Oh well, we hope the OP called the authorities and got the situation sorted out amicably.
