THIS GUY SAT NEXT TO ME AND WAS VERY OBNOXIUS, SEEMINGLY INTENTIONALLY SO...KEPT LAUGHING TO HIMSELF LOUDLY OVER AND OVER ...AND THEN started snorting and sniffing like he was snorting snot from his nose...it was very despicable..and didn't apologize...didn't even try to be a little more quiet..it was really something to behold..very annoying..very tiring....you ever experience that? somebody sits down next to you and without ever having met you immediately decides they don't like you and are going to try to let you know how much they don't care about you ? That's what it seemed like this guy was doing to me. And the problem is that when you are at a library computer, depending on the time restrictions, you can't always quickly & easily move to another computer (assuming there is another one available), ...or other times you have your flash drive or phone connected and are in the uploading process, and to stop and move to another computer means you have to abort the process and start over (very time-consuming)...so if a jerk decides to sit down next to you, in some cases he has a "captive audience"...all you can do is turn up the volume in your headphones and try to ignore him...; sometimes you can complain to security but it's usually subtle obnoxious things that they can't do much about other than tell him to "try to keep it quiet"...; what causes some people in the world to try to be obnoxious? Attention-seeking? Lord we pray for this young man whatever his situation may be...whatever issues he may have..let him come to You Lord this Christmas time !
