5I visited a couple's house at a roadside in Sri Lanka. It was very small, dirty, hot, and noisy; it looked like a garage.
When I visited another house one day to talk to the residents, I was surprised that it was the house of the couple I mentioned above. I asked them how they could afford to buy such a big house. The husband told me that a very rich man came (had come?) to see him and requested to exchange his tiny house, including the land,
withfor his three-storey house, for thea reason (only the rich man knows) known only to the rich man. The poor man agreed and the deal was done.
1) Is 'at the roadside' correct or should it be 'by the roadside'? I'd use 'by the roadside' or 'at the side of a road'.
2) Is 'done' correct? It's widely used.
I think 'sealed' is the appropriate word. Probably inappropriate. I doubt if there was any sealing, or even signing. It might well have been just a handshake. 'Done' covers all possibilities.
3) Are there any errors in the paragraph? I've marked them.
