Seriously, I guess you're now an expert in Spanish, lol. The use of "e" is also used instead of "y" at times. What both of you were saying was "hand and hand", instead of "hand to hand". The preposition "a" means to, at or at times with certain verbs such as "ir" which means to go. Now, let's talk about being wrong. The interchangeable use of the two prepositions, e and y, are both correct. Mono actually means "bun" or "monkey" in Spanish, depending where you are. I"m referring to the preposition, not the meaning of the phrase. And BTW, just so you'll know, the inaccurate phrase your'e referring to does have meaning but not what he was actually trying to say. I guess you're an expert in Foreign Language lol.,
