Looking for a movie were a younger bicycle riding kid gets hooked up with an older kid who has a van and just moves in with the younger kids home. There is a father and grandmother also in the house. The grandmother always wants to go for a walk. at the end the grandmother dies and at the funeral the older kid takes the casket for a walk as he said we promist her a walk i am taking her for a walk. Also the youger boy is trying to purchas the car his mom died in. Also i think the yonger boy has a crush on his teacher and the older kid with a van helps hook them up. Seems like at the begining the older kid throws an explosive at a cop but no one is hurt. Does anyone have any idea what this movie is??? Been looking for some time but no idea its name other than I think it is the older kids name.
