The vast vast majority voted against Brexit and are devastated, if not surprised, by how it has played out.
Luckily, getting residency was fairly straightforward, with the requirements basically being that you live and work / are retired in Spain.
The hardest part though is knowing that further generations are not able to exercise the same freedoms that we were able to. So many unlived experiences, friendships, marriages, children. That truly is the greatest shame of all.
