I was at a friends house Saturday.
It’s block construction, late 80’s early 90’s
inside the house all the bedrooms had an a/c vent, however atop each door was another vent. You could see through this vent into the bedroom, and visa versa if you were standing in the bedroom. It was just like useless vent hooked up to nothing.
What purpose would this serve? I looked for a gap under the bedroom doors and it appeared suffice for return air. Any ideas?
Just wondering

It's for return air.
returns... you don't always want to be pulling your return air off the floor...
