Twitter user R1A says she always wondered why her dad insisted on wearing the same old polo shirt all the time - until she discovered the reason.
Looking through her deceased grandfather's belongings, she found a photo album with pictures from her parents' honeymoon.
That was when she first spotted the polo shirt she'd learnt to hate.
Her dad had his green and yellow polo shirt on in several photos, right next to her mother who was wearing a matching shirt.
