The Twins are sooooo FAKE, they are playing up to this whole innocence 5 year old persona and some of the viewers are actually buying it...
Reason 1: The twins are 19 year old girls and the majority of 19 year old girls do NOT act like that...since there is such a thing known as maturity.
Reason 2: The twins are both students in a university and the fact that they cannot identify between a bird and a moth is a bit puzzling...unless they are playing up for the cams...also they were in the middle of the IQ range out of all the housemates...so it obvious that they are playing this whole "clueless" act.
Reason 3: The Twins have copied their little "acts" from Bring It On and Mean Girls to be entertaining but the fact is that they cant even be their own person so they have to become a different person i.e the girls from mean girls or the cheerleaders from bring it on.
Reason 4: The twins are obviously steering clear from having real conversations with other housemates in the house...not once have they had a decent conversation with a housemate in the house..and when they talk to other housemates they use this babyish tone but in the diary room there tone changes. Hmmm..why would the twins steer clear from having real conversations...would it take their whole innocent, 5 year old, friendly, Girly, Pink persona away...?
If you dont believe the twins are fake then trust me they have fooled you.
