It's mostly like this:
Wake up early in the morning (if you've slept that is) and greet your parents as if you've just got back from abroad after two years or something
Two minutes later, my mother is screaming at the top of her lungs for everybody to get ready so we're not late. Eid prayers. There's always, always one or two of us who will be left behind. There's always someone late. After we've come back from prayers, my dad starts giving out Eid gifts (in cash) to the kids and helpers, and another non-cash gift for the wives (and they give him nothing in return!).
Then we drive in our separate cars to my grandparents' place, where the whole family meets. When I say the whole family, I mean direct uncles and aunts, their wives/husbands and children (only first cousins). The grandchildren, including myself and my siblings, would be 30 people in total. The younger ones get to meet very often. The older ones, like myself, don't meet often, so Eid is a time for us to meet the older cousins (males and females) and catch up basically. (In our family, we don't usually marry first cousins).
After having our breakfast together, we start receiving guests (second cousins and other family members). That's when we're separated. The men go to a separate majlis, and the women occupy the living room. After lunch, the grandchildren (younger ones) use the second floor to play and the rest of us (older ones) just hang around until it's evening time. Then it becomes our turn to visit other families. And that's when it gets boring. Your mouth is aching by the end of the day because of the cheek-to-cheek kisses you do. You can't stop if the other person hasn't stopped yet, and it's not like you really kiss the cheek. You just make the annoying sounds. (With men it's easier. They just do the nose-kiss, which is not really a kiss. They just make their noses touch. If you think that's weird, I don't care?
)
Like this, so you don't freak out:
All the above is frequently interrupted by children ringing the outside gate bell for a "3eediya", symbolic amount of money the elders hand out to kids who come knocking on Eid. Just a custom.
After the compulsory visits, the cousins (older ones) usually hang out together. Either we go for dinner or a movie, or both. A few years back, we spent the evening and the day after at an uncle's farm. We rented a couple of scary movies (I didn't watch any) and drove all the way to al-Dhaid (farm-area). Some of the crazy cousins (males of course) will sometimes suggest sand-duning before sunset, or camping in the evening. We go by votes.
In any case, this year I missed out on all this.
