So last night I recieved a text message last night with the same area code and same first three digits as my number asking "who is this?" I then asked back "who is this??" because I did not recognize the number. A few minutes later they send me the same message "who is this?" I started to get pissed off and said "I don't know who you are. Stop messaging me." Then they wrote a laughing face and said "okay I was just wondering who you were I thought maybe I knew you." I didn't reply back I said okay whatever. A few minutes later I recieve a text message from the same area code just a different number asking again "hey who is this?" At this point I was PISSED I called the number, first time they did not answer second time a girl answered and I asked "who is this?" she said "who is this?" I said "who is this?!! you keep sending me text messages!" she said "I asked first" I then said "look, stop playing on the phone okay." She then said "you would know who I was if you told me who you were." I then hung up the phone.. so far today I have not recieved anymore text messages, but if I do, what should I do? It is kind of creepy.. also I forget to mention this is actually my moms phone, not mine.
