I have tried to use the word "buygone" in my sentences. Would you please correct my mistakes?
1. Sometimes David would meet his old friends and they would exchange the memories from bygone days.
2. The city is filled with contemporary architecture, but in some parts of it, the vestiges of bygone age could also be found.
3. Laura did not like to talk with her husband about her bygone years in the orphanage.
Sentence 3 doesn't really work with "bygone". I don't think you need an adjective there at all. She just doesn't like to talk to her husband about her years in the orphanage. It's obvious that those years are in the past.
We don't use "bygone" very often at all, save for the phrase "Let bygones be bygones".
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
