Been there, done that... Took my friend flying while he was writing up his PhD thesis. He'd never been up before either, so we opted for a local jolly in the C152. Did some low flying, some steep turns, then climbed up to show him the sea. The usual things.
Got back and it was getting dark, so I asked him for some help putting the cover on the aeroplane. He knelt down to pass me the strap under the tail, and when he stood up he knocked his head on the flap. I laughed heartily, then checked he was okay... then promptly walked into the flap on my side. He did the right thing and laughed back. Then I walked round the other side of the aeroplane to check the cover, and straight into the other wing. I had two very interesting shaped bruises on my forehead for days.
The worst one was after my first solo, when I climbed out and stood straight up, forgetting how low the wing is. I too saw lots of pretty flying things, low level, high speed.
