Alex do not like to socialize to other people,simple,but if it benefits her,then she'll go! She also like to think things carefully and cautiously,to make sure nothing bad happen or fail in her plan and getting different situation instead,that is not according to her plan,because she absolutely hates it when it doesn't go according to the plan. Do not show emotions to other people,even to her closest friend or family,because she believes it's a sign of weakness,so you could consider her a 'cold person' for the people believe,because of her not showing any emotion,not even boredom! the people decided already that she is.
