Not the same, but my grandma used to call at least daily with a computer issue. I finally started acting totally incompetent and pretending to not know. She moved on to calling a different cousin. Ha.
I did this to my mom for the KB/GB issue. That one was just crazy.
My sis and I share a phone plan and I think she thinks I own it or something. About a month ago she was asking me if we could do three-way calling. I had to look it up... just like she could have easily done. I gave her the account info and password.
My gut is to help people, but damn - sometimes I just lose all sense of humanitarianism around my family.
