I'm a coffe lover and can't stand tea, not even the smell of it. It was during an illness I had when I was about 8 years old, that I just found tea vomit inducing and never found it anything but since that time. I used to drink it before that and so that one illness seems to have changed me forever.
Sadly that was back in the days when everyone drunk tea and very few drunk exotic stuff like coffee. (Back then coffee was an expensive thing that was only ever made with hot milk. In fact what we make now with instant coffee (Water with a bit of milk) was referred to as a water coffee and saved on milk. Now it's just called coffee and the normal way to have one outside of a fancy coffee shop.)
Back then whenever I'd go around a mates houses, the parents would just make me a tea without even asking as it was that normal and a party of every day life. I had to either refuse it and put up with the social disgrace or drink it, gagging all the way.
