Rule reminder
Unstressed pronouns (mi, ti, lo, la, gli, le, ci, vi) are neutral and go before the verb. Tonic pronouns (me, te, lui, lei, noi, voi, loro) add emphasis, are used after prepositions, and after words like anche, solo, proprio, nemmeno.
___ aiuto ogni volta che posso. (I help him — neutral, regular)
