Being a single parent is a difficult job, and one that folks don’t really get breaks from, which is why it can often feel exhausting. That’s also the reason they might sometimes reach out to friends and family for babysitting help and be a bit demanding when they do.
This is what happened to one woman who told her friend that she couldn’t look after her baby, but got stuck with the kid anyway when the mom just drove off. The woman couldn’t believe the audacity of her friend, and it caused huge cracks in their relationship.
