I am 38 and my girlfriend is 18. Because she's smallish and likes to wear her hair in braids or pigtails sometimes, she could easily pass for 14 or 15. When we hold hands or kiss in public, people sometimes look at us with disgust. How do we deal with the rude behavior of people who comment on something that isn't any of their business? We're both adults, and don't like being made to feel like we are doing something wrong when we aren't.
