I am 15 and my sister is 13. Lately we have noticed uncanny likenesses in 
eachother. We often come out of our rooms wearing the almost the exact same 
outfits. At least three times a day we say the exact same thing at the exact 
same time. We even liked the same guy! How do you explain this? Could there 
have been an incident in the fertilization of the egg (me) that would have 
caused it to split and be fertilized two years later? Could we possibly be 
unidentical twins?
