Hi. Children do that in nursery if it includes or in school. It is not easy to write in Latin alphabet for every Russian, even though modern generation. "why you can write in abc alphabet without problems if it´s not part of your mother tongue." we can, because English is the international and popular language, we have it everywhere and mostly, people do know a little of it even if they do not need it AT ALL. Sometimes too many stuff in English on the streets (btw, too many loanwords).
