I did not respond.

I received a text saying HI also and i did respond because I use to live in the area code and i have friend with this area code so i thought maybe it was someone I knew. I text back and they told me to add them on IM and ID was taylorflirty2. i asked who it was but the only response i got was that they had no signal. i text stating that they had enough signal to say they had no signal but got no response.  who is this
