Rabbi Aryeh Lebowitz

and Rav Shimon, he lived with Rav Shimon Shkaab for a couple of years when he was writing the Shari Yosef, and Rav Shimon used to take a matzah and divide up the matzah to all the people at the Seder, to have a kazayis from the one matzah.

Five or six different kazayis from the one matzah.

And he wasn't a Hasidic Shereba, who was a Baal Meifes, whose matzah was growing.

He was just giving the matzah.

There was that one-fifth, one-sixth of the matzah equals a kazayis of matzah.

So it is kidai, the truth is, to be a little more machmir on how much a kazayis is,

for the first kezais midoraisa on the first night, but not necessarily for the other kezais.

And as the Mishpura says, we should be machmir for a chatzibetzah on the first kezais, on the first night, and then afterwards, a shlishbetzah would be good enough, a third of a kebetzah would be good enough.

Again, not going into all of the details of Shiurim, it would take a lot longer to do that.

Another Seder misconception is that a lot of people think that if you do this, if you just lean into the air, that that's called Haseba.

Hasebo is actually a luxurious type of sitting.

They used to sit on these fancy couches at their table.

And it's really more like a lying down kind of thing.

But certainly at the very least you have to be leaning on something.

It shouldn't be something that's very uncomfortable, that's awkward.

It should be comfortable.

It should be something that you, at the very least you need to be leaning on a cushion or something like that.

and not just to lean in mid-air, so that is another misconception.

Number four on the list, a lot of times women believe that they do not have to eat a sheer kazayis of matzah and marar.

I think it's the fault of those of us who are super-machmir in the sheer of matzah that turns the women off from wanting to try to eat a kazayis of matzah, because they look
