I have twin 8 year old grandchildren that seem to be as normal as any other children their age. My story is about twin girls I met who were neighbors. They had a strange twin language where each spoke half a sentence. Twin A always started the sentence and Twin B always finished the last half of the sentence.

Growing up together it did not present a big problem because they were always together. Then they each got married and lived apart with their husbands. Twin A had a minor problem as she had to learn to continue speaking and finish her sentences. Twin B had a major problem. She could not talk because she couldn't start sentences. It took many months to get over the hurdles.
