Typing mistake

Well this happens to those who are too much into chatting......and you dont realize it that you have typed wrong. once while chatting to a male colleague, instead of typing one sec, i had typed one sex....lolz....until then i never realized that "C" & "X" are neighbors in the keyboard...i hope it happens with everyone and not me alone!!! well i was embarrassed as the colleague didn't reply even after telling "sorry typing mistake". whats the big deal??? this happened with me thrice....you see, always in a hurry to get things done.
