Old Story... yet interesting

I was on my way to bedok swimming pool when i walked past a mum and a son.

Walking passed the swimming pool;

Son: Why there are so little in swimming pool today???
Mum: Because it is the chinese 7th lunar month.
Son: But why Chinese 7th lunar month cannot go swimming pool. Does ghost come out during the day?
Mum: No, but usually we chinese will avoid the pool if not, the ghost will pull u down into the water. Also cannot roam ard at night... or they will follow you back home.
