9. They Will Project Their Feelings on You
When they are having a bad day, you will be influenced by it as well. They will not hide their emotions and usually, they are angry or pissed at something. They will shower you with their negativity, even if you are not the cause for their bad feelings.
10. They Are Not Intelligent
As they do not have any interest in others and the environment around them, they cannot hold a conversation for long. All they can talk about is themselves and their work. They also do not like to be taught new things, because they do not like to feel stupider than the others. They like to explain things, but the sad thing is that they do not know a lot.
