That’s why people leave voicemails… you leave a verbal note of why you’re calling. And if the receiver prefers to read a text about it, several services transcribe voicemails automatically good enough to get the general gist. Or they can listen to them.

The point is that people usually don’t set out to ruin your day or misbehave, and you cannot control other people’s experience, expectations and preferences, only your own. So it’s on you to know yourself well enough to manage your boundaries appropriately with technology/tools, and possibly communication, and not to blame other people for “missteps”. When what they are doing is likely perfectly within the realm of reason to them.

Especially if they have a disability and calls are easier for them. If you have the disability, you can communicate your preferences but don’t expect people to know immediately. Set up your tech accordingly to communicate your needs. And acclimate where you can.

If things “escalate”.. well… it’s likely your fault. We always need to look at our part first.
