Last night I showed our DC a pic of me and their dad when we were both 13 - we've known each other a long time - and back then - we both look the same height - I'd say we're both around 5ft 1 - 5 ft 2.
Since then the height differential between us has been massive - at 14 my DP was around 5ft 9 I would say - his final adult height is 5 ft 11. Me? I'm still 5ft 1! So I've not changed since we were 13 - but he's gone - well massive !! AIBU to be surprised at how we were once similar, now massively different ?
