Mother and father in law are abroad and sister in law agreed to carry out proxy vote for referendum in their absence. It does mean travelling 10 mins by car to polling station but she said she was happy to do so.
She has double checked with in laws and now MiL voting Yes and FiL voting No (was undecided). SiL has decided not to vote (but to pretend she did) as the votes cancel each other out.
I am unable to come up with a counter argument beyond the fact that for me it is about voting and the incredible privilege we have in this country to make our voice heard. I am struggling to put it into words beyond that so SiL won't hand over the cards to me to let me put the vote in instead (assuming I could anyway?).
AIBU?
