Yes. Make sure to ask them if they're okay AFTER you laugh, not before. This is VERY important!
(this does not apply if it's an elder or a baby)
Only if you are friends with them and after you've made sure they are ok. If the answer is yes to both, laugh away.
Depends on the situation, better not laugh if they fall because of you, if you don't know the person, or if they got hurt
of course jnot because they could be seriously hurt
See if they got badly hurt first.
Only if the person who fell starts laughing about it FIRST. Otherwise, it shows you're callous and have no empathy. And the "injury" factor doesn't matter one bit-- They can still be emotionally hurt from embarrassment... and nobody enjoys being humiliated or ridiculed.
Depends on if they get hurt or not.
If they aren't severely hurt and they laugh about it too, go ahead
Depends. He old/young was the person, physical condition, and how close you are to them. But yes it's cool lmfao
Sure, that's the kind of thing that makes life worth living.
