always good to take a female.

I agree with Ruben, but have no idea why he would assume a good accountant would be female.

I'll cite the highly dramatic strip search, with female officers present, of the woman who cops "mistook" as an aggressor (in other words, she was aggressive to the responding officers which makes her an aggressor) where the documentary maker showed the husband saying, "She felt penetration" and referring to it as a "rape".

If it's copper, the only turning is going to be the valve if it's on a male/female fitting.

Your lease should specify who can actually BE on the lease (your female tenant).Since the boyfriend is claiming that he "lives there" your tenant is breaching her lease.This can be grounds for an eviction if you wish to go this route (which is likely to be more successful than simply asking them to move along).  

During the wait I kept seeing guys come get this stuff and I can't help but strike up conversations with a few and some were contractors whose female clients prescribed this, some were husbands told by wives to get this.

If the store won't send female drivers to an area after dark, it's probably not a prime real estate market! 

It will require a generator if the power is off, an air compressor, an adaptor to go from air fittings to female hose threads.  

However, I have to agree with the others that your letter to her was loaded with emotion and while it is understandable you don't want to stoop to her level.It's not all that unusual that a female tenant might want a landlord present when an unknown male repairman is there to attempt to address what the tenant claims is a repair issue. 

They were about about preference for investors who have a connection to Germantown and for female and minority investors.
