Thia kinda sounds like something you would do if you wanted your coworker to stop calling you outside of work. She may be messing with you so you leave her alone
That is such a n asinine argument I don't even know where to begin. She was in the privacy of her own home, and the OP called her. She very well could have already been on her way to the bathroom when she answered the call. What, should she just pee on herself, or maybe just hang up on the uptight bitty who apparently can't stand the sound of peeing without being insulted. Again, I say, grow up.
Pissing LOUDLY
she is not a she is she?
She could have ignored the call and then called back after she was done. There is that option.
