Looking for a movie I saw when i was a child

Im talking about a movie from probably the 90’s i dont think it reaches the 00’s…
Cant even remember the plot I only have 2 scenes in my mind where 2 kids were having a sandwich (talking about wounds or scabs, cant remember) and one of the kids is struggling to get money and decides to cut the grass in the backyard of an old woman… Sorry I cant remember more
