Hmm. What to make of this? "Sisters spread happiness while brothers breed distress, experts believe." Or this? "Having a sister makes you happier and more optimistic, say psychologists."
I grew up without sisters. Three brothers, but no sisters. Well, my sister was born when I was half way through my freshman year in college, so I didn't really "grow up" with her. And, apparently this makes it hard for me to cope with my problems. Could be true. I'm still not coping with the Mets of '06, '07 & '08, but like leaves on a tree I can't help returning in the spring. More problems in '09, undoubtedly and I'll probably still have trouble coping.
