Tom and biking

I always feel stressed when I get a call from Tom in the middle of a dog walk, or when he is out with the dogs and calls back home... Usually the call is a good news, but I'm always afraid that something bad happened when he calls at that times. Last Thursday I was deep in the woods with the dogs when Tom called me and said that he had a bike accident - a dog charged at him, he hit the dog with full speed and went over the handlebar down to the ground. He was o.k but his collar bone may have been broken. I was at least 10-15 min away from the car and was running back quite worried. It was relatively cold and he did not have warm clothes as he was biking. I saw him standing and walking on the sidewalk with his bike down on the ground. The dog was gone by then.
Fortunately no broken bones, but still recovery time will contribute to no climbing for a few weeks.
And now I will answer phone calls during the dogs walks with even more emotions than before.
Tom will still be biking...
