Today I was working with a Jr resource to show him how to get a tab on nav menu in an app. I kept on searching for that custom object tab in nav menu but could not find it ....even though that tab was created ( thats what I thought at that moment ) ....later realized ...I was looking at the wrong place ...I was looking at RENAME TAB section of setup and not under TAB section and trying to figure out why my TAB is not showing up on Nav menu even though its there under RENAME TAB section ....Later I realized my mistake

I have been in this ecosystem for 6 years now and felt so embarrassed on this mistake or mix up

What are some of the embarrassing stories you seasoned professionals have ?

EDIT : After reading the comments , I am glad I am not the only one. I am still feeling very weird about that whole situation.. EDIT 2 : Thank you for the Reddit Gold !!!! my first time.
