context: Washing clothes is a frequent activity that used to be done by hand but now can be done using washing machines and dryers. Some people with lots of children wash clothes everyday. To wash clothes you need to gather all the dirty clothes and use a laundry machine. Some people have laundry machines at home and some people need to go to a wash house to use laundry machines. The wash houses have all different size machines and some take coins and other wash houses take cards. To wash the clothes you have to separate by color so that all the white clothes are together and all the colored clothing is together. Also if you have sheets and towels you want to wash those separately. When you find a machine that is the right size for the clothes you need to wash you add the clothes and then follow the directions to see how much laundry soap you add. Some people use liquid laundry soap and some people use powder laundry soap. You can even do a mixture or combination but make sure to use the right amount. After adding the clothes and the soap you pay for the machine and wait 30 minutes to 1 hour for the clothes to wash. After the clothes are washed you still need to put them in a dryer unless they are delicate clothes that are not supposed to go into the dryer because they might shrink. You take the clothes and put them in the dryer but make sure not to put anything that might shrink. For the delicate clothes you hang them to dry. After you put all your clothes into the dryers it is time to fold the laundry! This is important so the laundry will be nice and neat and not wrinkled. If you have long pants or nice shirts you can put them on hangers instead of folding.
