A funny korean

      A few days ago a new colleague came to our company,he's a korean,and learning chinese.

      I introduced him to everyone.when I spelled my full name,he asked me"why does everybody call you '小李'?".I was laughed by him. no problem,i can explain it in english.i said because I'm the youngest in our office,it just a nick name.when I'm old ,they will call me '老李',and... $#@&*$$

     But one day,a colleague call me'小李呀'.just my luck,he heard and asked me why.

my god!it really gets me,how to translate,who can tell me.

    I think,if he hear someone someday say '斜儿坡,马儿坡',won't he ask me why?

what should i do? i'm dead meat.
