A common thing you’ll find many Jews wear on a daily basis is a skull cap, called a Kippah (meaning “dome,” in Hebrew,” and a yarmulke in Yiddish. In Reform Judaism, a Kippah is often seen as a choice, but it is important to note that most do elect to wear one and in nearly every other sect of Judaism it is required. Quite simply, the kippah is a constant reminder that G-d is above you always, heaven is always above you and around you.
I wear one from moments after I wake up until it is time to sleep at night, it is important to me, not just for the stated reason, but also because it identifies me in public as a part of the Jewish people and as a Judaism believer/practitioner. It’s important for me to let other Jews know that they are not alone in the world, even if they haven’t seen another Jew in some time and the Kippah does that.
The one easily identifiable fixture of Jewish life, especially amongst the diaspora is the Kippah, so I wear mine everywhere I go, even if I am just in my house. It is identifiable, it is spiritual, and so in my honest opinion, the Kippah is nondebatable!
To others, they may elect not to wear a Kippah and that’s fine too, it is their option in what enhances their spiritual connection with Hashem, but in my house, my kids and even my wife chooses to wear a Kippah.
