Did you first leave a voicemail, text, or email as well? Most of my time I am busy. Either sleeping, working, relaxing (TV, games, friends), and only a small small fraction of my time am I doing nothing to such a degree that if pick up an unknown number call. Especially in 2020s due to spam callers.
I've noticed some people saying "kids don't pick up phones anymore" and really, no, we don't. There's more efficient and reliable communication modes available. If I could pay for a sperate set of phone numbers that were text-only, I would have that instead.
