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.
