Greeting someone is something that we do every day – at times, consciously and at other times, subconsciously. We greet people; we welcome them. Gestures such as welcoming a newly-wed bride into her new life generate as much warmth as a child’s playful laughter. I am not saying that all that we are welcomed by is good for us.  The first offer of a cigarette can be a trap for many and a seductive look can be even harder to resist. However, every tunnel has two openings; if the darkness tempts you into it, the light at the other end is just as welcoming.
