There's many ways to hurt someone - you don't have to physically hit that person, in fact sometimes I think emotionally hurting someone is more hurtful than physically hitting someone. Of course this is my personal opinion. I have listed a few ways where we can emotionally hurt someone:

1. Ignore - ignoring someone when they greet you or talk to you
2. Impatience - Hasting someone to come to an end
3. Belittle - Looking down at someone's work, ability or contribution
4. Absence of affirmation - no good word said for work being done
5. Interrupting - not giving chance for someone to finish their opinion. Cut in abruptly because you think the other person's idea is not important
6. Back talking - talking/ laughing about someone's weaknesses behind their back

hmmm.. I can continue adding to this list.. but so far this is what comes to my mind. What about you?
