Premature

There is a huge tower block with lots of signs on it offering luxury rental flats near where we live. Since my stuff has arrived from Hong Kong (hopefully intact, but you never know until you open the boxes) and the flat we are currently in will not accommodate all of it, M. and I decided to go flat-hunting over the weekend. We chose to drive to the huge tower block with lots of signs.

We spent a few minutes working out where the rental office was, then where the vistor's parking spaces were. As we were pushing the door of the rental office, an old man wearing a checked cap nodded at us as he passed by and said,
"Good morning!"
I thought it a bit odd as I walked up the carpeted stairs with M.. Then we saw the lobby was full of old men and women. One old gentleman was picking his nose. The white-haired receptionist looked at us curiously.
"We're looking at apartments for rent," M. said to the man. He grinned.
"I'm afraid this is a facility for the over-fifty-fives," he said. "Come back in thirty years."
We walked back down the stairs feeling sheepish. M. kept muttering to himself,
"But you can't tell it's an old people's home from the outside. It doesn't say anything on the outside."
Back outside, the man wearing the checked cap nodded at us and said, "Bye!"
