When you invited him over to your dorm to hang out- he thought that it would be a little boyfriend-girlfriend hang out time-....not that you would lay on your bed reading on your phone the WHOLE DAMN TIME- and he can only assume the worst- you've got to be reading some kind of somthing smutty, considering you'll be reading with a blank face and randomly freak out for a few sceonds before going quiet without saying aney explanation to him at all- and you just keep reading.
