`topic` and `reply` belongs_to associations on `SillyReply` are defined with the same `foreign_key` (`parent_id`) and `counter_cache` (`replies_count`) columns. This would cause unintentional side-effect (e.g. saving `SillyReply` object would cause double increment `replies_count`), so it is better to avoid that side-effect.
