"Did I just put my hand in your face?"

The Doctor has a very strange way of always getting his arm (or something else odd) in my face. A couple weeks back, we went out to get a TV remote, and the plan was to go to Homebase (it's in the same shopping area) if we couldn't get the right one at the first shop (I can't remember what is was). We found it at the first shop, though, and on the way back to the car, he suddenly stopped and put his hand out right in my face pointing across the parking lot. It might have bashed me if I hadn't moved when I saw it coming.
"Do we still need to go to Homebase?" he asked - half to himself, I think. He realized we didn't, and then turned to see me quietly leaning away from his hand. (I'm fairly used to him absent-mindedly doing it, and I know it's useless to say, "Hey! Get your big hand out my face, Doctor!" so I just smile quietly to myself at his strangeness.) "Oh!" he said (but not with alarm or anything - just as if he was realizing something he'd forgot). "Did I just put my hand in your face?"
"Yes!" I said, half laughing and half annoyed. "And you almost hit me!"
"Oh. Sorry." He smiled fairly casually.
And the night before, I was talking to him, and he just stuck out his hand and rubbed (or maybe ruffling-ly patted) my head, from the front, so that his arm was in my face. I think my eyes kind of went big and gave a little jump of surprise and confusion. He said it was and 'affectionate pat' or something like that, but I'm not a dog, am I?:) Then I remembered that scene in The Hand of Fear, when the Doctor and Sarah are talking to the manager of the power station, and she's sitting on the table next to him, and as he starts talking, he grabs the top of her head and turns it toward the people their talking to! She looks a little like I must have look when my head was suddenly patted. So, I put the pat down to the fact that he's the Doctor, and he's a bit (a very big bit) unusual.
Then, last night, he had turned our old table upside down to take it apart (we've got a new one), and he asked for my help unscrewing the legs. I unscrewed the last one and then sat back while he did something with the detached legs. I didn't really know what he was doing, though, so I lent forward to look. Then, he picked up one of the legs and moved it over me, right over my head! I hadn't really been looking at the time, so I wasn't sure how close it got, but I had a strong suspicion that it had missed my head by about an inch! I looked up and the Doctor was staring at me.
"I missed your head by a hair's breadth!" he said. This time he did look almost alarmed.
"I know."
"Sorry." Well, he was back to casual. And although I can't find the exact episode right now, I know that there's been at least one time where the Doctor had almost bashed Sarah on the head. One of them may have been when he picks up the stick in Pyramids of Mars, when they're trying to find the deflection barrier. Being around the doctor can be dangerous, but it's also fun!:)
