I have a keyboard for a tablet and I keep it in my pocket. I somebody stole my tablet and I ran after him (he did it as a joke) so my keyboard fell on the floor and a few pieces fell out of the keyboard. I can’t return it. I is the person who I ran after chayav or not?
Although the incident is unfortunate, the person who “stole” the tablet is not liable for the damage.
This is not a case of direct damage — the person who took the tablet did not know that the keyboard was in your pocket, could not have expected it to fall out, and did not do any action that can be considered even negligent with regard to the keyboard.
Therefore, this is not a case of “garmi” (direct causation of damage) or even “grama” (indirectly causation), and the person is not liable to pay.
