I thought that after more than a year working from home I’d eradicated the habit.  However, spending just half-a-day in the office yesterday has reawakened my almost automatic impulse to dial ‘9’ before phone numbers (which our PBX requires to get an outside line).  Unfortunately, doing this at home results in a screwed up call.

It’s amazing how such a small bit of reinforcement can cause an old habit to come back full force.
