I have kids and sometimes it’s important thing from a doctor/school/whatever that I want to get.
However, I’m lucky that my cell phone area code is nowhere near where I live, so if I see an area code near my phones area code, I know it’s almost certainly spam. If I get a call from near where I live, its almost certainly legitimate.
Regular doors with handles don’t fail open, there is just an Intuitive and common way to manually open them, which seems like the short coming here.
