I'm a huge fan of space but I'm scared to death that one day I'll refer to Neil Armstrong as Lance
Have you made mistakes like this before?
Yes, I once called Neil Armstrong by the name of Lance.
That is a simple mistake, I wouldn't make too big of a deal out of it. Otherwise, when something is really scary to you, people might not believe you!
I really want to make a big deal about it so I can prove to people that I am not a space idiot.
I totally understand not wanting people thinking you're stupid or don't know what you're talking about, but this is a pretty silly mistake. If anyone actually judges you for making this mistake, I'd say they don't deserve your energy.
