This is exactly what my husband is like when he gets Hangry. Sometimes when he eats, he is so happy that he hums, and doesn't even know it. It's so adorable! My husband is an eating machine with a very high metabolism. Most people would be envious because he eats like crazy, but his body immediately turns the food into fuel, and he is just a powerhouse of energy! So this is close to reality: Before Food vs. After Food.
