The father and grandfather argue after the slide show, and the father goes to pull down the white sheet that was hung over some drapes to act as a screen. He pulls it down, along with the rod and orange drapes that the sheet was hanging from. Moments later, the drapes are back up in place and hanging perfectly straight, without enough time for him to re-hang the drapes.
When the girl has been crying and the grandfather is comforting her, he wipes the tears from her face. In some shots, you can see where he wiped the tear. In other shots, a tear that has tricked down to her chin. In some other shots, she has a tear that hasn't traveled so far.
When the grandfather attempts to fix the small outboard motor, the rope he is using snaps leaving portions of the rope still attached to the motor. A moment later, the rope fragments are completely gone.
