What? she was fixing strollers?? ask her to STOP immediately and pray none of the customers will sue if the stroller breaks and child is hurt in the process. Your little sister has no idea in what kind of trouble she might be and could be criminally liable and state attorneys do not play nice when it comes to neglect of children wellbeing. Unsure which state this is in, but most have 5 years statue, so if she stops selling today she should be in clear by May 30, 2029. Please pray for her!
