I think that you may find that Tamera`s a little more vibrant and energetic, but I`m much more likely to go up to a person and say, Hi, I`m Tia, nice to meet you". Wheras Tamera is like...well ...she`s a little shy. She`s down to earth. I`m more extroverted and she`s more introverted when meeting people. Even with a fan I`ll be like, "Hi! How are you! How are ya doing?" and Tamera`s in the back thinking, "Let`s see if this person`s okay, then I`ll come". That`s how she is. I take the first step."
