I don't understand movies like "It Takes Two" and "The Parent Trap" and "Baby Geniuses" where these twins switch places and the parents DON'T FUCKING NOTICE!!!! I seriously don't understand how someone can replace your child with a stranger that looks just like them and no one notices. It's always the butler and/or the nanny that notices and the parents are completely clueless. Wtf? I know it is a movie and that is not how it is in real life but I just want to know how someone could not notice. It is one thing for friends to not notice (although I had twin friends in middle school and I could always tell them apart) but their PARENTS?
Also, in the case of "The Parent Trap" how do you separate your kids and never get to know the other or never let them know their sister. Twins are not interchangeable. Having one child doesn't make up for knowing the other.
I have a friend with 8 year old identical twins and she can tell who is who from the back of the head on the other side of the room.
