I … himJapanese puts the action at the very end of the sentence, so this phrase is a common way to start saying what you did to or with "him" (彼, kare). 私は (watashi wa) sets "I" as who the sentence is about, and right after 彼 (kare) you must attach a small marker word to show his role, like に (ni) for "to" or と (to) for "with". For example, 私は彼に会った (watashi wa kare ni atta) means "I met him," and 私は彼と行く (watashi wa kare to iku) means "I'll go with him."
