In 7th grade I had a question once and my teacher said he didn't know and he'd get back to me. And then he did! And I was so excited that he'd gotten back to me, but I'd also forgotten entirely that I'd asked the question in the first place; it was just a passing idle curiosity. For some reason he got really upset about this, and looking back I guess he must have put considerable time and research into finding out the answer, for something that I was really just spur-of-the-moment wondering & completely forgot about 20 minutes later. Although I think he didn't realize that the fact that I'd forgotten the question didn't really diminish the joy I had at receiving the answer days later.
Anyway, it was during us studying the U.S. constitution and the question was about the order of succession in the case of the concurrent deaths of the president, V.P., Speaker of the House, and President Pro Tem of the Senate, so that it went to the Cabinet; I was wondering what order the Cabinet officials succeeded in. The answer is the order in which the positions were created, so Sec of State first, then Sec of Treasury, etc. I didn't remember this all these years later; you can find the info here: https://www.usa.gov/presidents#item-35877
This is not an interesting question. An interesting question is whether they ever got back to you.
