It is "Forgetful Friday"! What have you forgotten?

What an inverse tangent is used for. As well as most high school math.

How good the song The Dutchman is. I’m listening to it now, Rebbel. I remember that I sent it to you once.

Are you sure it’s Friday? I thought it was Thursday!!! ;)

I forgot to put the refrigerator deodorizer in, until you jogged my memory.

@Tropical_Willie Me too. Thanks.

I forgot it was Forgetful Friday!

I’m trying to forget many things!!

Huh?

I forget what I can’t remember.
