Father Like Son Experience out on the road

To tell you the beginning. OP was pulling out of door and they pull up in front of OP at the same time. OP gives the courtesy 2 beep beep on the horn to show they are wanting out. Give a hand signal too trying to communicate to the driver. Other drivers son comes around their trailer and immediately flips OP off and opens their trailer doors. Rest of the footage is what happens afterwards.
