I bet it was a crabby old lady. When I was younger, my family lived in an apartment complex and we had my uncle/aunt and cousins from Tucson visiting. We all went to the complex park to play. The "complex crab" came over and yelled at my uncle that he wasn't a resident and if he didn't leave she'd call the manager. My uncle explained that he was visiting my dad but she didn't want to hear it. I told him not to worry. She was the local crab and was always threatening to call the manager on kids and adults she felt "didn't belong." Its been 15 years since we moved and AFAIK she's still there being a crab.
