I watched this a few years ago in school. I don’t know if it was a short film or if we just watch like a 10-15 minute clip of the movie. It was very Irish.
A boy and girl are getting ready to leave. The boy is stalling and playing with a little toy car. He says he doesn’t want to go. Eventually they leave with just their dad. The three of them meet up with another woman and two other kids, a boy and a girl, near some train tracks I think. They are the mans kids with another woman. The mans son is just realizing this but his little sister doesn’t know. The man and all four kids go to some father kids party thing. The girls fight over their dad. On the walk home they are all holding hands and the one girl squeezes the other girls hand too hard on purpose.
I’ve been searching forever and I cannot find any info on it. I would guess it is circa 2000-2017. Most likely 2008-2014.
