One of the best reasons to subcribe to the Wall St. Journal is an every-Monday column called Real Time, written by Tim Hanrahan and Jason Fry. For those of you who don’t–here’s the best bit today. Link: WSJ.com – Real Time.

One of the great things about cellphones is they let you fill up time that would otherwise be wasted: taxicab rides, running errands, and so forth. (Of course, one could say these are great times for contemplation, and sometimes that’s even true.) This isn’t just for business — commuting after a long day at the office can be a great time to catch up with that pal you haven’t chatted with in a while. This can be done with the best of intentions, but the person on the other end of the phone may see things quite differently. It’s nice to have an old friend or grown child call to say hi, but it’s less nice if that old friend or grown child blithely announces they’re in an endless line at the DMV. There’s a difference between "I wanted to know how you’re doing" and "I have nothing to do, entertain me."
