messy neighbours and visitors

I don't think tonight will be good weather-wise but, regardless, there's not much point going out: the houses flanking me have all their backyard lights on.

I've talked to the neighbours to the east many times but they're once again running their lights all night. I have to get tough with them... Maybe I should write a letter...

To the west, I have visitors. Diane and Mark and kids are on vacation; they have some house sitters living in. They have turned the back lights on. I need to explain to them the situation, with respect to astronomy. Those lights shine right in my bedroom.

It's a bit too late to call them now.
