Most people know how to do their own laundry by the time they are 12. Many younger than that Also, if a college student doesn't know how to do their laundry, that is largely the parents fault. A vast majority of teens would 100% learn to do their laundry from YouTube if their mom just stopped doing it for then and didn't take the time to teach them.
