full!
does it bother you when you get that comment in public? it sure bugs me. you just never know what to say because yes, your hands probably are full holding a baby, pushing a grocery cart loaded to the brim, having to lug a purse the size of texas, or whatever the case may be. but if you say "well yes, they are" it is understood that you mean you don't want your hands to be full. if you say "no, they are not" it's probably not true, or the other person will think it's not really true.
sometimes i just smile and don't say anything, and then people will try
