Vicious Dwarf Pine

So we have a temporary mail man. Today he came by while we were outside, so we exchanged pleasantries. He was about to leave when he decided to pause and tell me my tree was going to get huge. I asked him which tree, as there are several, and he pointed to my dwarf pine. I admitted that it needed to be transplanted, as it is getting a bit large for it's current location. That is definitely not an emergency, something I plan to do next fall or spring. He continued, "It's going to break up the concrete with its roots . . . and . . . " Uh, bust out a window? I gently corrected him, but I mean come on mister, are you really going to tell me how to garden? You, sir, are now blog fodder!
