Many stores sell them, but once a store gets a shipment of yo-yos in, they're usually go quick. Because so many students are bringing them to school, many middle schools havebanned them.
Teachers think that yo-yos are a nuisance and that they interfere with learning.
There are many kinds of yo-yos. There are just plain yo-yos and there are automatic ones. Most kids prefer to buy the trick ones. I think that yo-yos are the same as toys, which were already banned from school, so I agree with them being banned.
