My family all voted REMAIN.
DH did for work reasons mainly. I did because it is what i have always known and quite frankly, life for me was okay. I had no 'quarrel' with the EU.
DM did in the end despite being very much a LEAVE voter. I asked her why, sort of disappointed that she didn't stay true to herself, and unlike many over 50's, as the analysis has shown, she decided that because she doesn't have much time left compared to me, DH and DCs. She decided that if DH and I were absolutely sure it was the best thing to do, then she would rather believe in us than politicians.
Not sure about MIL. No DF, FIL, siblings, sister/brother-in-laws to speak of; we're a small family!
TBH, I have no ill feeling against those who chose to leave. I made a choice based upon what I believed to be right and so did the 'leave voters'. Nobody did what they did to intentionally screw over the 'others'. Everyone did their best to make the right choice. Nobody knows for sure (yet!) whether BREXIT was the correct path to take. Time will tell.
So, I am not in the camp of blaming others and getting into the trend of name calling. What is done is done. Keep calm and crack on! Everyone now needs to ensure the best is sought and we don't f**k things up!
