Apologies in advance for any typos and\or mistakes!

I'm visiting a friend in London, and he just got the flu. I want to make him some tea to help him feel better, but I am very confused by the instructions he gave me on how to make Tea the English way, and not sure if he was delirious when he gave me the instructions or trying to test my resolve to care for him.

I have a few questions:

- Is the water meant to be boiled? (My grandmother used to say that "Tea is a peaceful drink" so boiling water is a no no, because of the "violence" in the bubbling water - I assume that what this means is that the temperature of the water should be below 100Cº).
- Do I brew the tea first, then add the milk? Or do I brew the tea after the water and the milk are in the cup?
- How long do I leave the tea to brew before I remove the teabag? Do I remove the teabag at all?
- Why don't english teabags have strings? My friend said I was supposed to use a strange pair of tweezers with round flat ends to fish out the teabag, but I can't tell if he is being ironic or delirious (and the teabag is meant to be left in).
- During my first attempt, he asked for "a spot" of milk, and I followed the instruction. But he then said it wasn't enough milk, and "a spot of milk" is not really "a spot", but about 1/4 of the mug. Is this accurate measuring? Are there other measures of milk than "a spot"? How much are they?
- Are you allowed to put lemon or honey in the tea?
- Is he allowed to have both honey and two sugar cubes in the same tea? Or is he ruining a perfectly lovely tea because he's addicted to sugar?

Thank you so much for helping me creating the proper cup of tea (for English tastes).
