     It's Saturday afternoon. Tanya is going to the laundromat（自助洗衣店）on Lincoln Street. She
needs to wash her clothes.
     There are many people inside the laundromat. Everyone is washing clothes. Tanya has two loads
of laundry. One load is for colours, and the other is for whites, but Tanya sees only one empty washing
machine.
Tanya thinks, "I don't want to wait for another machine. My loads are small. I will put them together
in one machine."
     The washing machine stops after thirty minutes. Tanya opens it and takes out her clothes. Oh, no!
Her white sweater isn't white anymore. It's pink! Washing the whites and colours together is not a
good idea. Now she needs to buy a new white sweater.
