Peri, your weak tea story reminds me of when I was at Uni. At the time we lived in the country, so I moved in with my bachelor Uncle who resided in Perth, our capital city.
In those days you could get "instant" tea...like instant coffee. (Horrible stuff it was) He also liked his tea very weak, he would only use 1 or 2 granules of the "tea" in the boiling water, add a couple of saccharine tablets and a splash of milk.
I decided one day to make him a "special" cup of tea...exactly as he did it, WITHOUT any tea! Just hot water, milk and what I
thought were his saccharine tablets. He drank the stuff and didn't notice any difference so I told him what I had done.
He just laughed, but then pointed out that the tablets I had added were not saccharine, but ASPRIN which he kept in an old packet.
Didn't get a headache for weeks after that!
