On a serious note, I think being neighborly could mean a lot of things but to me it's simply lending a helping hand without having to be asked. For example, my next door neighbors were gone for a month (they informed me they were going to be out of town) so I watered their lawn here and there, and if they got a package delivered, I held onto it for them until they returned.
As times get tougher and people become more desperate, or sociopathic, whichever, I find myself shying away from being my affable, kind generous human self, sharing and caring as in the last year in trying to just be kind and help or ask for help, narcissistics have ruined my sense of charity, grace, and, well, saftey!. My first reaction is to reach out. Say hi, ask how you're doing, and mean it. I'm the kind of person who if your tag is sticking out of your shirt, I'll apologize as I tuck your tag in. Let you cut in line. Give the change you cant find in your purse/pocket. It's a battle every day to resist the urge to "look the other way" instead of being open to an exchange of kindness for fear of being hurt. So, right now, I'd say just being kind, basic acknowledgement as you pass someone on the street or at the store is a start. I feel most invisible in public. It seems some people actually think there is no one but them in the universe, and it makes me sad. I just wanna say hi, wanna play? But those days are gone for now. Maybe someday by some miracle, well be able to be free to be kind and enjoy our neighbors, brothers sisters ??? I hope so.
