маленькая просьба / a little ask

besides, "добрЫ" is simply a plural (short) form. Full is "дОбрые", short is "добрЫ", as "вы" is a plural noun.

P.S. our discussion in a fact is a good opportunity for us native speakers to refresh russian grammar

Thank you a lot ! I didn't know about these "short" adjectives !
