Why do some guys talk so close to my face?

Anonymous
I sometimes start talking to males, and our chat starts at the normal 3-4 feet of distance. As we talk we are both smiling, laughing, and chatting. (but not flirting from my perception) Then some guys gradually get their face closer to mine, (like about a foot away from my face) as they are talking. (Once their face is so close to mine I step back, to keep vital distance.) Note: our voice volume is perfectly audible.

(This situation might happen to others with females, but it hasn't happened to me yet.)
