Off late C got into habit of writing in official mail .."Tried calling you" if she couldn't reach a colleague over phone to clarify some doubts..
Now one fine day, C would have been in some great hurry. She contacts S over phone. S didn't pick up the call, may be because she was beezeee.. so C thinks its better to drop her an email.
So as a newly acquired habit, C starts with "Tired calling you. blah blah blah"
After a week she wants to refer the mail she sent S for some reason. And to her astonishment she finds the 1st opening line of the mail as
Tired calling you. blah blah...
C was shocked for a moment of what could be interpreted on the other end as it sounded very unprofessional..and laughed it out loud though..
Just a slip of alphabet between "I" and "R" changed the interpretation of the whole sentence which was really short to change the meaning all together..
C just laughed out that instance...but such is life....
