If you believe in fairies, they will show up sooner or later.
However, because fairies do not believe in Time,
They may come long after you have stopped believing in them.
In fact this is the most likely thing.

Fairies are both curious and easily bored.
They are fascinated by objects of all kinds.
For example, they are fascinated by clothes, although
It is a fact that fairies do not ultimately care for clothes.

However, because they are curious,
They may try on all of yours,
Then discard them on the floor next to the hamper
Or maybe somewhere else

Which is in fact the most likely thing, because
Fairies do not believe in Order.
Very few people know this about fairies,
Mostly they assume that fairies are just very hard to please.
