Bootoo:
Sorry to ask such a stupid question, but here goes. Last week I got up the courage to go to confession for the first time in something like 25 years at an Advent Penance Service at my church. Now that I have finally gotten over that big hurdle, I know that I need to start going regularly so that I don’t get too scared and start avoiding it again. However, it has been so long since I’ve been in a confessional itself that I’ve forgotten how the logistics work. I seem to remember that there is one light that indicates that a priest is in the confessional, and another light that indicates that a penitant is in there… or something like that? I would hate to make an idiot out of myself and walk in on another penitant, or be waiting in a confessional with no priest there

. I’d appreciate any help anyone can give me.
Congrats on returning to the confessional. As the saying goes, “Be not afraid!”
I’m just curious about the Advent Penance service. Was it a penance service that followed with individual confession? I know in one of my former parishes, these confessions were open air, but still private with the priest due to the screen. But, they weren’t held in a confessional because the lines were so long. Some years ago, the Vatican clamped down on penance services that did not provide for individual confessions and wanted it clear that anyone with mortal sin on their soul must use individual confession for absolution. Our penance services continued, but people stopping in for public absolution came to an abrupt end and that’s when more priests were brought in to hear individual confessions.
Most confessionals have lights on them. There is typically a light indicating the priest is in (can’t recall color). Then, when the penitent kneels or sits in the chair, it triggers the penitent’s light to turn red, from the green that it was.
As indicated above, some of the more traditional churches still have the old boxes where people could enter on either side. The priest would then slide a window and close off one side and open the other. However, in my traditional parish, these were modified so that on one side you may knee, but on the other, you may sit. It is no longer used the way it use to be with two people on either side.
There are some really great guides online too. The first two are examinations of conscience using the 10 Commandments.

This Examination of Conscience, written by Fr. John A. Hardon is unusual in that it uses the Theological Virtues of Faith, Hope, and Charity, rather than the 10 commandments. I am finding this one particularly helpful for the stage I am at right now.

And of course, a general guide and related links, written by Fr. John Zuhlsdorf:
