Not sure if joking or a troll, either way that's certainly not what stoicism is. Stoicism is about the fact that when anything happens there is the physical cost (car breaking, getting sick with the flu, getting a divorce), and an emotional cost (getting angry, dwelling on it, disconnecting from reality). Stoicism says you can control the latter and improve your life as a result.

Probably the best way to manage it, is to be objective about your reality. And then there are other tools, like reframing, taking setbacks as challenges to improve and become more resilient, and many more.

End of the day, we're tiny ants on this space rock, enjoy it, and take it as it comes.

This isn't Stoicism. There's no eudaimonia in that way of life which is a fundamental part of Stoicism.

Together with Schopenhauer being considered a "pessimist", this is a recurring misconception. Not sure where you discovered that something like you described is stoicism, but it surely doesn't fit. "I'll pretend this person doesn't exist" is probably closer to a mild form of depression than to one of stoicism's main tenets, i.e., focus on what you can control, don't let yourself being derailed by negative emotions arising from facts outside of your agency.
