Already told you he wasnt using his laptop, no need to reply anymore
Not every person has as easy a time with English, or language in general, as we do. Some things in life, just need to let them go.
Every language uses periods and commas. E.g = Hello, how are you. / Cześć, jak sie masz.
Not everyone on this forum speaks English as their native language. Forgive them some errors in grammar.
