a quiet birthday?

Liam hasn't mentioned his birthday (and doesn't know that the child has) and therefore is expecting to just quietly note his change in age.

He was happy to provide presents for the child, and has already hung the child's drawing on his wall.

But his general plan is to stay in his room and relax. Perhaps take one of those bubble baths the child is always talking about.

[Do you knock? Throw the door open? Somehow catch him in the bath because the Mansion is evil?]
