Do girls in your chapter not get more than one little sister if it turns out that way? I mean, it seems nice to be the only child... but if you really think one of the girls is super and she already has a little, don't think that means you can't request her as your big sis. My Big Sister already had a little sister when I joined, but I thought she was absolutely smashing so I picked her as my big sister anyway--and you know what, it is SO awesome having a TWIN SISTER too that I can't imagine it any other way!!
