(1) Where are you going, sis?
(2) I haven't seen my little sis since November last year.
(3) So the first thing I'm going to do is rest up and then get back to training and I'm also looking forward to a fortnight in the sun with the little sis and if anyone can cheer me up and make me laugh, she can.
(4) Your little sis will learn she can truly count on you.
(5) The sis and I thought we'd do the noble thing and suggest we all meet for discussion, extend that olive branch, that family was too important to let things end like this.
(6) And if you need a whiney, loud-mouthed woman to repulse those pesky telemarketers, throw your little sis some cash.

(19) Even if the guy is amazing, you and your sis share a lifelong bond.

(21) I am a twin, and my twin sis is my best friend - I do everything with her.
(22) At least now I won't look like such a beached whale on the beach next month when I head for sunny Spain with the sis who, incidentally, is about a size 8!
