Spot on im not a RC but that looks like a good old fashion confession to me one mate who is not from a christain background is dating a pinoy girl and he does not get why she confessed to a couple of petty things in her past. He thought it was some kind of cover. Ie he could not imagine a Girl he knew from his past mentioning.
I take that as a respect thing from a pinay who as Dom says normally only confess to the big bloke up stairs and his representive in the local church in a little box.
