That's really cute, but I wonder if Clownpiece understood the meaning of it.

Once again, that's not how it works

When she speaks about a particular situation or event, that situation will eventually proceed to reverse itself, through whatever means possible. If she speaks about an attempt to achieve a goal, it will fail in some way. If she speaks about something bad occurring, it will be resolved in some way. Due to this, she tends to not speak too much and always chooses her words carefully. Note that it is the situation or the event she talks about that will be reversed in some manner; it is not that the opposite of what she says must occur.

But then if she talked about Clownpiece never coming back, would that make her come back again?
