Got to work this morning and was at my desk around 7AM. I hadn't turned on the 'sugar phone' in several days, because not much is happening anyway. But this morning I decided to just turn it on. I saw I received a text at 1:13 AM saying 'Hi how are you, just wanted to let you know I was thinking about you'. Not signed, I did not recognize the number. The only person I knew from that area code is Issy, an old friend that lasted about 1 month and have not seen in a long time. At least that's what I remember, but who knows, as I am getting a bit senile in my old age. I just responded 'hi, how is it going' because i didn't want to be impolite and say 'i have no idea who you are, can you please sign your texts next time, if you are Issy I have not seen you in 3 months and I was not able to memorize your number'.

Etiquette: Always be professional and sign your name or give a hint, especially months after your last meeting, otherwise you may have been deleted already.
