The clues were all there; I was just too inexperienced and ignorant to put two and two together. But these things are always so easy to see with hindsight.
A few days before this photo was taken, I had pulled on a pair of jeans to find they were uncomfortably tight around the waist. Unwearably tight. I was surprised but didn’t think much of it.
Then I saw the photos from the trip … And I was shocked at how pudgy I looked, and strangely busty (for me).
It took me another 6 weeks to figure out the reason why.
