Was it real or just my fantasy?

There was this scene from "How I met your mother" where Ted and Robin made a pact, a marriage pact. Telling each other that if both of them turn 40 and still single, they would marry each other. 

I don't know why, but I have this memory that I have actually made this same pact with you. Kinda frustrating as I'm not sure whether this actually happened or it was just a false memory (I guess I projected you and me in Ted's and Robin's shoes?). I can't just text you to confirm this as it would be pretty weird; plus, if I ever ask you about this, there's a high probability you'll never speak to me ever again! Haha! Nevertheless, I miss you friend! I miss every good memories we had together! IF that pact was real, and both of us are still single at the age of 40, I will cheers to that! :)
