Still in love after all these years

Took my mum to the doctors & whilst we were waiting to go in, a lady came out and met a man who was waiting for. They must have been in their 80s. He stood up and gave her a kiss then held her hand. As they were walking out, he realised he was on the wrong side of her and move to her left and linked her arm.
It was such a lovely scene that I just had to follow them and take a picture.
