shabbat - practical examples of a grama



I was trying to give a practical example of a grama the other day, and couldn't think of one. While there are plenty of devices which employ gramas deliberately (grama switches, shabbat electric wheelchairs, etc.), I couldn't think of a simple example people actually encounter in normal life that would be considered a grama. Can anyone help me out?



Answer



If you leave someone's front door open, and their dog runs away, that is a gramma (bava kamma 55b).


If you startle someone and they bang into something and hurt themselves, that is a gramma (bava kamma 56a).
