I texted my friend today and both of the texts never said that they were delivered beneath them but it seems like they sent. It was odd too because when I would send one, the blue progress bar at the top got about 3/4 of the way and stopped for a couple seconds, then it would just disappear, not finish "loading"or whatever you wanna call it. But they look like they sent. I don't wanna call and seem annoying! Anyways, does this mean that they're not in an area where they get service or their phone is dead or something or does it mean they blocked you?
