i agree. not everyone wants or needs to watch. and let's face it, if there's a boob out in public, guys are gonna look. just some discretion and a little more privacy.
i was at a little restaurant in college where table space was limited. i was alone at a big table when a couple asked if they could join me. sure, why not. all of a sudden, mom whips out this giant boob and little timmy starts nursing. no warning, no discretion, nothing. it was uncomfortable to say the least.
