Examples

• Два часа, потраченные на электро́нное письмо́, кото́рое не займёт и одной печа́тной страни́цы, не по́вод для го́рдости. Э́то, скорее, посла́ние о твое́й со́бственной неспосо́бности писать связно.Spending two hours writing an email that won't even take up one page of a sheet of paper is not something you can write home about. It's more like you're writing about your own inability to write coherently.
