Email

My work email has been a bit weird recently - it keeps getting messages returned to my inbox saying undeliverable even though I never sent them in the first place. I delete these straight away without opening them because hey they could be anything. I think theres a bug of some description in the server of the mail company. But none of the computers I use are infected cos I keep checking them, more regularly than it says you need to. Today I had one which was from someone who I don't know and the message read "STOP TRYING TO INFECT MY COMPUTER YOU FUCKING MISERABLE PIECE OF SHIT". I didn't do anything. Honest. I feel angered at. I hate people shouting at me...
