Давно хотел найти, но как-то забывал всё.

Russian does not use complicated sentence structures like English. You can normally say exactly what you want with just a few words. For example, in English to be polite we would say something like “can you please pass me the salt”, however in Russian they would say something simpler like “give salt please”. Speaking so directly may even feel unusual for an English speaker, however it is perfectly normal, just add the word ‘please’ to be polite. This makes it easy to say what you want in Russian, and it will probably be correct. Less words also makes listening to people easier, as you can just pick out the important words.
у меня есть вариант объяснения: русские все скифы и вандалы и слово пожалуйста - единственный оставший гонорифик в языке.
