Our neighbor was accused that he allegedly shot his brother with a knife. They questioned all the inhabitants of the entrance who heard that evening. The grandmother from the third floor (well, in every entrance there is such a grandmother who knows everything about everyone) immediately confidently stated: no, say, Mishka could not do this. Mouse is good, always greeting!
In general, keep in mind: you say hello to grandmothers - you provide yourself with an alibi for all occasions of life!
