He wants to be reminded of an event two years before it happens for cripes sake and was going on a long annoying tirade against the software maker for not allowing it.
Fine. I'm a jerk (but he's an idiot).
At the very least, he fails to understand the concept of "the reminder."
I think it's a completely valid request. In fact I want to be reminded of things 25 and 50 years from now so I buried time capsules lined internally with Post-It Notes in my back yard. The 25 year time capsule contains just one Post-It that reads: "Don't forget to open the other time capsule in 25 years."
