I am thrilled that I might have shared some information that may help ! You can certainly use those "what ifs" skills in that situation - when your boss had to leave ! Like SO WHAT IF I am here alone, I can lock the door and who will kow......or SO WHAT IF the phone rings - let the answering machine take it, I can say I was with a customer (if that is appropriate), etc etc etc. Keep on keepin on !!!!
