When I go to the supermarket, my son makes me so angry!
He wont stand still when queueing to check out, and while we're waiting to pay he tries to grab chocolates or play with the food at the point of sale. If I let go of his arm he runs off and looks at the magazines or gets in the way of the people going out of the door and plays with the automatic doors.
I try telling him what my expectations are, but he gets me so angry because he always misbehaves at this time, so I end up holding his arm really tight and he starts fighting with me. He is nearly 4.
