  Among the (in)famous differences between classical and quantum mechanics,
quantum counterfactuals seem to be the most intriguing. At the same time, they
seem to underlie many quantum oddities. In this article, we propose a simple
explanation for counterfactuals, on two levels. Quantum Oblivion (QO) is a
fundamental type of quantum interaction that we prove to be the origin of
quantum counterfactuals. It also turns out to underlie several well-known
quantum effects. This phenomenon is discussed in the first part of the article,
yielding some novel predictions. In the second part, a hypothesis is offered
regarding the unique spacetime evolution underlying QO, termed Quantum
Hesitation (QH). The hypothesis invokes advanced actions and interfering weak
values, as derived first by the Two-State-Vector Formalism (TSVF). Here too,
weak values are argued to underlie the familiar "strong" quantum values. With
these, an event that appears to have never occurred can exert causal effects
and then succumb to QO by another time-evolution involving negative weak values
that eliminate them. We conclude with briefly discussing the implications of
these ideas on the nature of time.
