It all started with a bet my father lost to me when i was 14 (ca. mid 90ties). He was an early adopter for almost every new cell phone and i wanted one, too. I don't know what the bet was about anymore, but i got a cell phone:
It was bricky and heavy, but it was able to send text messages (SMS). I am sure i was the first kid with a cell phone in my city, i hid it in the beginning, people would stare at me, when i was calling someone.
After some months a girl in my class also got a cell phone, and we would text all the time (instead of writing small notes as the offline kids did). Her name was Tasya and she sometimes was kinda devilish, but still a very sweet girl. That's why i called her Taz,
the tasmanian devil once in a text.
And in her reply she called me ChrizZ (instead of Chris), because she didn't get the reference.
That nickname stuck with me forever.
