♪ ♪ So, what have you been up to lately?

>> Uh, playing games with my family, mostly.

We have this one game where I kick a soccer ball off the balcony and my dad tries to catch it in a wheelbarrow.

>> Wow, that sounds so... so... >> Fun!

I know.

>> (sighs): I wish this virus thing was over.

I am getting so bored.

>> Hello, Francine.

Muffy, ready for our trip to Crosswire Motors, where prices can't be beat?

>> Be right there, Daddy.

I have to go.

Today is a humongous sales event.

>> That's right.

And my Muffikins is the best sales event decorator in Elwood City.

Oh, that reminds me.

Now, where did I leave those special... >> Okay, just need to grab my purse and I'm ready.

>> Do you have your mask?

You're gonna wear a mask, right?

>> Only sick people need masks, Francine, and I am not sick.

>> What?

>> Although I did stub my toe in the pool.

I have this little bruise, which you can totally see... >> Earth to Muffy.

>> When I wear sandals.

>> Earth... to... Muffy!

If you're going out in public, you 100% need a mask.

>> But why?

I'm not sick.

And I don't like how they look.

>> First of all, you can be sick and not know it.

You can have the virus and feel totally fine.

Second, without a mask, you could spread it to someone who will get really sick.

Like Buster, who has asthma.

Or Mrs. McGrady, who had cancer.

Or your grandparents, or someone you don't even know.

>> But shouldn't they wear the masks?

>> Of course, but it doesn't help if you're sick and you don't wear one.

The only way to keep everyone safe is to wear a mask.

>> But they make my nose sweaty.

>> If we all do our part, we can get rid of this virus.

>> And they fog up my sunglasses.

>> Just think of all the people who look up to you.

Your fans!

>> You're right.

I am such a role model.

Daddy, I'm going to need a mask before we go out.

Could you possibly locate some sort of... >> I took the liberty of having some made.

Hand-dyed and -embroidered.

Only the finest for you, Muffin.

>> Ooh, très chic.

How do I look?

>> Like a kind and thoughtful person who cares about other people.

>> Great!

But seriously, how do I look?

>> Perfect.
