Someone who's who I am?

I got a text message yesturday the person saying "hi gurl" I replied with "who is this?" they responded with "natalie perez" my info and then I asked again "Who is this?" they replied with "I see you ;)" and then I said "if you can see me what do I do?" they replied with "write about music". So this person knows who I am and what I do for a living except the number does not look familiar to me. What should I do?
