Just a side note---home invaders/scammers sometimes dress up as someone from a company, so please be very careful.
When I was in college, my close friend and her roomates were attacked and robbed. They were living in an apartment building (known college student rental place--so good target for scammers).
They had a knock at the door one day, and a man in coveralls and cap with clipboard said there was a gas leak. He claimed to be from the company, and said he needed to check their apartment to see if it was there. They let him in and walked away--never once thinking he could be dangerous.
He walked into the kitchen, grabbed a kitchen knife from the counter, and then attacked them. He tied them up, and proceeded to ransack the place.
The good news--aside from being severely traumatized, and sporting some nasty brusies and scrapes,they were not seriously harmed. He did however get away with their cash, passports and other valuable items.
The three college girls were an easy mark, and they did not stop to question him further. My first question to my friend (when she was calm enough a few days later so that I could chastize her) was WHY you let someone in who was checking the gas--when you have radiators and OIL heat???
Come to find out, this was not the first time this had happened in their area, although to my knowledge this scum was never caught.
My husband works for a utility company. They are required to carry and SHOW their ID.
Anyway, did not want to hijack your thread. I just wanted to share some info which might be important to someone later. ALWAYS ask for ID, and never assume a person is from wherever. Its easy to fool people.....and I would rather accidentally be rude to someone, then find myself being the victim of a crime.
And--a person who does not at least keep a safe distance from barking dog, sets off a bell in my head. There are evil people in this world--never be complacent....
