Breaking people's windows is wrong.
Jeff remembers that he forgot his Keys at Mike's house last night and Mike is now at work.
Jeff wants to get his keys back before the day is over.
Jeff sends Mike a text telling him that he forgot his keys there and asking Mike to meet him after work.
Jeff drives over to Mike's house and breaks a window to enter, so he can retreive his keys.
Mike is happy to help Jeff out and tells Jeff he'll come home at lunch and grab his keys for him.
Mike comes home later that day and finds his property damaged, angering him and making him feel unsafe.
