We are going away for a few days and a neighbor offered to watch our apartment and cat, refill the food dish etc, only problem is her boyfriend that she lives with, he does drugs and often has people over at all hours of the night, people we don't know and seem to be questionable characters as they just sit around doing drugs and drinking.
I really don't want my keys in their apartment within these people's reach, we completely trust my wife's friend but her boyfriend and his friends, we do not.
We know her friend just wants to watch the apt and have her own space as the BF is almost always home and wants to watch the digital TV (we have 5 channels that play new movies just released to dvd).
We just wouldn't feel safe having her BF have access to our home is what it comes down to, how do we say no thanks without being rude about it, we obviously have to have someone look after the cat, I'd just prefer it to be family.
