Synthetic example:

"Вот его, нет, не допустили (сама знаешь, почему)))"

My translation:

"But him - no, they didn't let him in (of course you know why :)"

When I went from texting friends in Russian or Ukrainian back to English, I missed right parentheses as a smiley; one or two - hi), hello)) - to me are like a smile, by ))) and )))) there's some laughing or some other joke going on. Native speakers could weigh in; my native tongue is English.
