As someone who marginally understands parenthood: Sometimes kids just cry when they want attention.
Lots of my friends try to balance their kids and their gaming and as their gamer friends we understand this means sometimes they will be called away or have sudden and loud interruptions. Generally they are considerate enough to limit our exposure but kids have a knack for circumventing any sort of counter tactics to their attention getting.
Crying kids aren't always actually in distress and parents generally have a good idea of which is which. ...
I appreciate the effort of those who do have kids to not expose me to wailing and screeching but understand it's gonna happen sometimes.
