This is not a threat, it's a warning

Hi, i'm Chris. I'm from Thessaloniki as you can tell by noticing my accent. I'm 22 years old and i study Mechanical Engineering at the university of Thessaloniki. I play the guitar, every now and then, especially when i want to torture or blackmail others. In extreme situations I sing, too. When i'm on a good or bad mood I listen to music. And most of all I love to share this wonderfull experience with my neighbours. I repeat, this is not a threat, it's a warning.
