I got a text as well today, saying very much the same thing. I insisted on a name, but never got one. If it happens again I will have one of the local authorities trace it as I work with a few of our local police and they would be happy to help.
Got the same message saying Hi :). THen do you do remember me...all i said was who is this and no response. My friend got the same message and the only way we are really connected is through gmail. So we were thinking that is linked maybe? I just joined gmail so would make sense.
I just got this message and I told them I didn't know anyone from Delaware and to never contact me again. I am not sure how or when this person got my number, but I wish they they did cus it makes me think anyone anywhere can...
