i guess this is bestowed by God.. from earlier times, men were inolved in the hunting for food & protection while the women folk were in cooking, raising a family.. this aspect gets them attached to their loved ones.. hence, they tend to get more emotional than goys.. moreover, even boys are emotional but since they are 'boys', they cant show it off that way.. thats how the male ego works.. while, it is expected of females to express thier emotions quite openly.. however, i see this trend is changing nowadays.. its getting the other way now!
