There are a few things that really REALLY trigger an almost Obsessive-Compulsive reaction in me. Watching people roll a cable the wrong way is one of them.
Whether it’s for work, study or for your own personal life, being able to type, and to be able to type quickly, is a life-skill, something that will benefit you always. In my line of work, it is essential that I can quickly document the situation that my customer is facing, to be able to quickly search for solutions, to be able to quickly send an e-mail or post an instant message to my colleagues for assistance. It amazes me that there are still so many “Chicken” (Hunt and Peck) or “Biblical” (Seek and you will find) typists when there are so many free resources available to build up this skill.
