If I get a text and I'm doing like, my homework or something a little, sort of, less important (though still something I'd get done), to me, then I'll check it at that moment, otherwise I'll probably read it and then wait till later to reply. If I get a call I almost always answer since you never know when it might be important. =P If I'm having a conversation via text with my friends, then I'll likely check it constantly.
