It IS on accident most of the time. I could be working on homework o stuff for college.That kind of stuff comes first in my book. Except when there is an emergency. That's when people know to just call my house phone and they get a response 99% of the time.
Depends. Sometimes I ignore texts, emails...etc if the person was a perra to me o hurt me in some way. I'll also ignore if I'm in class o really depressed o anxious to talk to anyone at the moment.
However in situations where I receive an correo electrónico about a message I have received on Facebook, then I tend to ignore it for a while, get work done, then go check it out later in the day.
I do however ignore almost every phone call on my cell that isn't from my direct family. I don't do talking on the phone unless it is important.
