World would be a better place if people realize -
That just because I am carrying my cell does not mean that I am available and have to take every damn call.
A call is not necessarily more important than the person sitting in front of you.
A call waiting does not necessarily mean the waiting call is more important than the current one.
And if I dont take a call - it is generally not a deep rooted conspiracy to offend that person.
I do not ride buses to get updated on stranger's personal details - neither do I go to movies to hear all these ringtones.
