You don't need to be a psychology student or a master to be able to take care of moments and create analysis out of them. You just need a few skills which can actually help you in winning everyone's heart and also with these you can understand the behaviour of people around you in much better way

1- Immediate reactions are always shared with the person closest to you in a group - If you are in a group and anything happens and the girl you want to impress just shares her first impression with the person whom she thinks is the closest to her so might be you have to get that person on your side first.

2- Having eye contact can actually keep the conversation going for long - Basically it's a hack that if you want her to just keep talking then you have to look her in her eyes and you will see that it will not let her stop.

3- Feelings and Thoughts are actually Contagious - When you are about to meet someone or you actually meet that person at that time your feeling or might be their feeling can conquer either of your's mind and it will change the way you were thinking because of the strength of the aura being created with you 2. So, having a good feeling before you meet someone can make them happy too when they meet you.

4- Chewing a Gum Can Actually Kill Your Fear or Nervousness - When you feel nervous of if you feel a bit scared to do or meet someone then you must eat a pack of gum before because it will trick your brain and it won't think of that feeling anymore and you can just chill then.

5- People's Feet Can Tell You When They Want a Conversation to end - If the person you are talking to has his or her torso facing towards you but not the feet means actually want this conversation to end. So, do mind it.
