Psychologically, “I’ll call you back” isn’t something you want to hear! People never seem to call me back. When I call them for the second time, I don’t want to offend them, so avoiding conflict I never ask them why they didn’t call me back, I called them for a good reason I usually want something. When people say “I’ll call you back”, sometimes they don’t mean it. What they really mean is: “yeah, I’ll call you back when I’m good and ready, or “you are not important enough”. Sometimes “I’ll call you back” can be interpreted as: “I don’t know “, and this means they will do the opposite of what they say, and never call you back. Excuses for not calling back are equally annoying. Someone today told me: “they were out to lunch. “ This is a favorite in the work field and this message usually means: “ They don’t want to speak to you”. It is often said by a colleague, who may be sitting beside the person you are calling, who really is eating his lunch. So when someone says to you: “ I’ll call you back”. Don’t believe them, and answer them with. “No, people never call me back, I’ll call you back”.
