Bruce was concentrating hard on the Sonic Screwdriver he was building. “You really think so?” he asked, looking up at him and smiling.
The Doctor nodded in agreement with fascination and excitation. "Absolutely. Build a sonic screwdriver is one of the hardest things possible to create, and you manage quite well.

I'm sure you will have liked it"
