take care and BS...

I think all of us are used or accustomed to certain good bye clauses/phrases, be it email, texting, chatting or any other means.. a lot of it has been shortened.. tc for take care.. ttyl for talk to u later so on and so forth right..

so recently i was talking to a friend of mine who i've known for a long time and we were just catching up with each others lives on msn and the conversation was wrapping up. I had to go off and so did he. then it was the time for the good byes. I said my good byes with a take care and a budusaranai (a religious phrase - that I'd say only to family and close friends depending on the person and the situation), and gave regards to the family etc. He in turn says take care (tc) and bs, leaving me with nothing but a ?

After a few minutes I figured and he sorta typed (guessing that I was confused) that BS is budusaranai, just that everyone had made it short.. im like wtf?:S?!?!? BS is Bull Shit in my vocab and in many of the people I know but this is new and does not feel right lol.. I got this BS phrase on an email sometime back too in which I ignored for a typo or something like that and never bothered to question about..

Quite interesting and understandable how people have shortened words up for texting purposes and stuff, without realizing that BS is bull shit for a lot of ppl.. if there's no space for something like that in a text msg I'd rather not say it.. anyway that's just my opinion..
