Continuity mistake: While Tina is at the grill and apologizes to her father for Jairo knocking him down over and over, Tina's wearing the single yellow hair barrette at her right side, but the barrette repeatedly switches sides during this scene. (00:19:45)
Continuity mistake: When Bob goes to Tina's "karate concert" ceremony, just as Jairo tells Tina she's next the clock on the wall reads approximately 4:27, then two shots later the clock reads approximately 4:33, but in the next shot it's back to the previous time of 4:27. (00:17:00)
Continuity mistake: When Bob goes to pick up Tina because she was late for work, Tina is wearing the yellow hair barrette at her right side, but after Bob's accident when she tells her father that she's so embarrassed, Tina's barrette is at her left side. (00:09:00)
Continuity mistake: After the "30 minutes later" mark, while Tina is lying on the floor in the overhead shot the large slicing knife is lying on the counter with its blade pointing toward Bob, but next shot it's pointing in the opposite direction. (00:01:05)
