Did you notice a basket filled with white head coverings for the women? When I attended, all women had their heads covered.
Didn't see a basket with head coverings, but all women did cover when they went up to receive communion and a good number were covered the entire time (maybe a little less than half).
When I attended a Coptic Liturgy in Egypt, only some women wore headcoverings for the entire time, but for the Communion all of them put headscarfs that they had taken with themselves.
no need to convert, we have the same faith!
By the way, you came in at the end of the Intercession hymn, which is the beginning of the Liturgy of the Word. And don't worry about your standing so much. Keep in mind that in my church we started at 9AM, finished the liturgy late around 12:30PM, took a break till 3:30PM and started the genuflection (sagda/prostration) prayers which finished at 7pm. You came on a major feast. It's not like that usually.
Wow, that's really long! And that's great you had prostration service in the afternoon, separately from the Liturgy (at least in EO tradition this serviced is presribed for the vespers, but currently usually it's done just right after the Liturgy)
I was just caught off guard I suppose, since the Byzantine tradition seems to abbreviate so much even on Pentecost.
Well, at my parish (that it's absolutely not any good model as it goes for the liturgics) we had 2 hours of Vespers and Matins and 3 hours of Liturgy and the kneeling vespers, so it wasn't so bad.
