i don't think I've ever blipped my Sister before.

Yupp - she's a weird one.
She went with her friend to Ikea the and got that guinea pig stuffed animal (she used to have a guinea pig named shamu...it died when her friend fed it Kashi or whatever it's called...that natural stuff). So she decided to come home and start bringing it around the house with her everywhere.
She's sane btw... Just in case you had your doubts.
She just goofs around to a ridiculous extent
