the acting was not very good at all, the guy was just walking around and doing regular stuff and he still managed to make it look not believable

some constructive criticism try not to go back to the same shot like when he is picking up the keys, it goes back to the same shot which looks bad, some of the cuts are a bit weird like this too and dont fit together. you can see the camera shadow in one of the shots walking down the street
i liked the sound when the time changed on the clock and the way it went like that at the end too. was there some sort of metaphor or something? or is it just "guy gets up, walks to the store, sees a random guy in the telephone booth, drops his groceries and runs back home"?
i hope this constructive criticism helps!
