Going to / Собираюсь

Sometimes it takes me hours learning new knowledge. It can be some simple things like drawing in Photoshop. Today, my London friend asked me about how to conjugate the grammatical construction ”going to”. “Can you write down the equivalent endings of собираюсь for each personal pronoun please”.

You may ask me why a British would ask me to teach him English grammar. Well, although many English speakers are quite messy with their characters, he is one of the more educated ones. What he needed was the Russian language!
While drawing an example table for him, I thought how easy the English grammar is in this very case. Russians would start adding numerous endings to their words/verbs. Brits outsmarted us here. They simplified the matter down to just 2 variants: with ‘are’ and with ‘is’. So, where we need to add those 6 endings they`ve got just 2 little bits!
