My name

Er, can you guys call me Sandria? I don like people calling me 'Aless'. I'm not quite comfortable with the name 'Aless' even though my name begins with 'Aless'. Why can't I be called 'Sandria'? My name is Sandria! zZzZz... You like calling me Aless but I don like. Simple, Alessandria. Cool? Thanks.
