Status Updates From My Husband's Wife

I'm sorry but who lets their 8 year old be outside by herself, riding a bike on the neighborhood street, alone, with no supervision? In what, presumably is 2025? We aren't talking playing with other kids in a group, or in a fenced in yard. This kid was alone for as long as it took you to have sex with your husband upstairs in your house? I'm no hover-parent but that pisses me off. Am I overreacting here?
