As a polyglot, that's not really the biggest gap in English - the one that's the most painful is that there is no way to distinguish between you, singular, and you, plural.

Regional dialects have taken matters into their own hands, with y'all/all y'all, youze, yintz, you guys and the like.

Also Indonesian has a very nice distinction that one would want in English - "kita" means "We, including you", and "kami" means "We, not including you". I sometimes find people in English writing or saying things like "We (not you)" or "We (including you)" to compensate.
