This strip is another episode of the "Violet evicts Charlie Brown" saga that has been going for some time. At some point, possibly when the art style became more detailed, this stops seeming cute and starts seeming cruel. It's not now because Violet has a change of heart, but eventually her reservations diminish.
Charlie Brown's playing with blocks seems odd here. Although he's represented as being very young, he and his friends more typically play cowboys or spaceships. Blocks are usually used for the (even) younger characters, Lucy and Linus.
Scribble of ire!
