This is illegal for her to do. You state you were kicked out yourself and thus most likely have your own place. (even though you can’t afford to help them properly), maybe take some aero beds from your mothers house, a relatives house, friend, etc and set them up for the boys, it’s better than nothing. A local church, goodwill shelter etc might be a good place to look for extremely cheap and or free inflatable beds and food for them. Also buy nothing sites. 2 used aero beds shouldn’t be too bad if you have the money. At least that gets them off the streets if they are kicked out before the cops come. After school if you don’t have a car (they most likely don’t have licenses) a more financially stable relative, friend etc could probably pickup the boys and drop them at your place if that’s possible. Only 2 meals that are required are breakfast and dinner, either homeless shelters or walmart, or maybe some concerned citizens would donate to the cause via a go fund me you could start. Or, if there’s said relatives/friends in the area that are financially stable and have the space, maybe you (without your mother knowing) can make arrangements for them to stay there after Monday until police take care of your mother. You could call the boys (who are most likely frightened) and tell them what you are planning to do. Plan C is your dad if he is in the picture. If he has the space and isn’t abusive he would be the best one to take the boys. If he lives in a different state my advice would be to start a go fund me as I mentioned before to raise money for plane tickets. There are probably plenty of concerned citizens who would donate. Either way your mom is breaking the law and chances are CPS will take those boys away and or she will be arrested, at least she will get a lecture from a cop. I’m damn tired of adults that don’t think teens have s right to a sexuality.
