No, you can't play.

Tierce: What are you doing?

Bravewolf: Nothing.

Tierce: But it looks like fun.

Mischa: Never mind.

Tierce: But you're playing. In the bed. Under the blankets.

Bravewolf: Yes. We are. Glad we've sorted that out. Now. Get. Out. Of. The. Bedroom.

Tierce: Can I play?

Bravewolf & Mischa: NO!

Tierce: I like to play under blankets.

Bravewolf & Mischa: NO!

Tierce: Well you don't have to be so mean about it.

Mischa: Apparently we do. Now get out of the bedroom before you get escorted out with some propelling force.

Tierce: Fine!

Tierce: ...

Mischa: AAAUUUGGH!

Tierce: Your foot is salty.

Bravewolf: GET OUUUUUT!

Tierce: But now you're PAYING ATTENTION TO ME! Why should I stop now?

Mischa: Apparently the philosophy of 'ignore him until he performs the correct behaviour' is not applicable to this case.

Bravewolf: Agreed.

Tierce: gets escorted out of the bedroom with some propelling force.
