Just ask.

If you send me a shout and I do not answer it probably means I am not here at the computer.. sooo coming back with a smart ass bitching shout as to why i did not answer is probably not going to get me sitting at the computer any faster, cause Um .. I am not sitting there.
I chose to not put up a status all the time of my current location or activity.. cause it is no one Freaking business unless i chose to tell you.
Have a great day!!
