No reason, I just feel its nasty.
Also it started to happen sometime when I was a brat, since my mother told me I had no problem with those animals before.
Yes. Especially in the new class which is full of girls. I just see my classmates having conversation, they are all standing in circle and are on their phones, and talking about something phone related. I usually can't fit in to conversations cause they are showing stuff to each other on their phones and when I come to take a peek, they go like the fuck dude, it is personal stuff. Probably isn't anything important. Also my 1st semester crush did it a lot. I'm talking to her and she starts texting with her friends and bf too. She told me that it is urgent and that she isn't doing that because she is bored around me. Happens a lot with other girls too. Sometimes I notice that the person has not heard anything I or anyone else said. I see that happening in other classes too. I guess starting a conversation is hard nowadays.
Wow, people like that will get shunned here.
Everyone always hang around with the same group in my class, but they don't mind "outsider" joining the conversation. I'm not close to anyone particularly except my old friends from high school, luckily they're all easy to approach.
The problem might be different here.
To answer your question, no, they won't text if they are hanging around with their groups, if someone do he/she usually ask for permission to do so.
But people here texting a lot if they are not having a conversation, everywhere, during class, eating, playing, even when taking a dump.
Basically, they will stop and pay attention if they have someone to talk with.
