First of all try and ask your mom If you can go outside.

If she says no, you can Netflix, but you don't only have to watch Netflix you can also watch Disney channel and prime vidio. There are also so many films you can watch on these apps like 

Wednesday ( Netflix)  Toy story ( Disney Channel) and so many more.

Since you can't go shopping you can go online. 

You can buy so many things like a new dress, some new shoes. But shopping is not only for girls also boys can buy.

You can also visit this app, storyjumper it is so much fun I do it everyday (that is how I spend my time).
