I always send Mrs Motties postal vote in for her.
Seriously, when we walk up to the polling station, we always take the dog for a walk. We don’t take her in so one of us stays outside with the dog while the other goes in, votes and then we swap over. Mrs Mottie always rolls her eyes when she is going in because I always say something like ”Remember what I told you - tick the top box" and we get some really funny looks from others that are outside who think I am controlling the way she votes. It makes me laugh anyway!
