Shameless beggar

We have awesome neighbors (Mark and Stacey) that live next door to us. They have 2 teenage boys and Cameron loves to go over to their house and bounce on their trampoline with them and play with their old toys. He almost always gets fruit snacks when he is over there, so needless to say, he wants to go over there all the time! Anytime we pull up into our driveway, he wants to see if he can go over to their house and tell them he is almost out of fruit snacks. Anytime we are on a walk, he asks to go knock on their door to see if they are home to get more fruit snacks. And now, anytime he wakes up from a nap, he yells that he wants to go to Mark and Stacey's house to get fruit snacks. He is a shameless beggar!
