__cato is just pointing out that there are disadvantages, since the comment he&#x27;s responding to isn&#x27;t aware of any. In fact, before their comment, I wasn&#x27;t aware there were disadvantages, all I&#x27;d heard is that there were advantages to being bilingual. You many think these are small things, but they&#x27;re interesting and they&#x27;re backed up by studies.
