Clarity regarding Aq Al-Walidayn

As-Salamu alaikum brothers and sisters, I want to know if for example, (1) your mother told you to put the milk on the fridge, and you don't do it because you're too tired, is this Aq Al-Walidayn? (2) and is shouting at a parent also Aq Al-Walidayn? (3) and is Aq Al-Walidayn a sin even if your parents forgive you? (4) or if you disobey them forgetfully? Barak Allahu feekum and Jazakum Allah khayran and remember, don't let this site distract you from your duties to Allah. May Allah guide us. And don't spend too much time in any answer or question just say what's necessary.
