People mirror themselves against others. Someone else whom you seem to influence is probably mirroring your actions. Observe yourself and others in your surroundings.
You will tend to notice some similarities.
Do you see people sounding the same, using similar words, wearing similar clothes and somehow having the same posture after hanging out together frequently? You probably see in campus, students taking a particular course behaving similarly. You can tell this is a nerd and this is not one. Such are the outcomes of public mimicry.
It can be a good thing for your success.
On the other hand, it could mean you are being too much of a beta male. Time to stop it and get other improved postures, wordings, habits and so on.
