Friends' teenage daughter making me feel awkward

I'M a 54-year-old man and currently in the middle of building a new house. Recently, I had to move out of my old place, as the new buyers wanted to move in right away.

But the new house has been delayed, so my two good friends said I could stay in their spare room until my place is ready.

They aren't the problem, it's their 17-year-old daughter. Whenever it's just the two of us in the house, she walks about in revealing outfits, pyjamas or just a towel after showering.

Her parents have big jobs, so often go away at weekends, camping or to a hotel.
