Out and about

Shopping or at restaurants I don’t pay attention to people. If I make eye contact people will say hi. We live in a friendly area. And with the baby they will anyway. So, I try to avoid people because if they say hi and I can’t, that's just rude. What do I do? I am in my own shopping world, as most people. But once in a while I will notice people starring at us. At first, I always think of some reason like oh the baby or something in the cart or if we brought the dog. However, my husband will tell me no people always stare at you. So, here I am thinking I’m minding my own business not looking at anyone in a bubble, as they are all watching me. Thanks Hun. Burst my bubble.
