My colleagues and I share the same telephone in my office. Conveniently, it sits on my desk so I am the "operator". I am so used to being polite on the office phone that whenever my own handphone rings, I always have the tendency to go "CAMTech, This is Avril speaking. How can I help you?"
It happened many times already! I can imagine how stunned my friends were to be hearing me speak that way. Please excuse me if I pick up your calls in this manner. Job hazard (职业病) you know.
