The biggest problem with Brexit was that we only had a vote of in or out. Little say on what the future would be or what sort of deal we would get, though many people gave their opinion on what would happen
Brexit still isn't done, there are still arguments over areas such as Northern Ireland
But there are hopeful signs that some politicians are willing to work together in the interests of The UK

I voted remain, I was disappointed that UK citizens have lost freedom of movement, but I used my own right 2 days before the initial Brexit day back in March 2019
I don't believe rejoining is a realistic option, but I hope that the UK and EU can have a closer relationship than at present, and I hope Dover doesn't grind to a standstill when the ETIAS scheme kicks in
