Thank you both for your responses! I'm not in a rural area and I've never had network issues, so a message not going through immediately would be unusual. I ran a virus scan (using the mobile version of the antivirus software I use for my laptop, so I know it's reliable) and it didn't pick anything up. I also checked data and battery usage to see if any apps were behaving strangely, but everything seems to be working the way it should. Aside from that one mystery message nothing strange seems to be going on, so I guess it's either a glitch... or a ghost.
