Its an annoying repetitive sound, and I could imagine it to be fucking annoying as hell.
And no, she's not getting batshit pissed (where the fuck did I say that?) over it, she's being annoying by it and I'm trying to find a solution. You wannabe machos really need to take a good serious look at yourselves if you don't want to be playing with your wet noodle and palmela handerson all your life.
Sending her away is not a solution. Why? Because I like her. (WHAT A CONCEPT!?) and like having her in the same room so that I can talk to her, or joke with her or try and comprehend the shit she's studying.
That is the whole reason for this thread, studying requires quiet, if i kept hearing mouse clicks i would be annoyed also, but if i was on the OP's side, i would do the responsible thing and try to find a solution just as he is doing.
