Ok, I'm going to contribute once more...

Around 17:30 Casper gets restless, he starts meowing, because it's daddy's time to come home.

-Meow!
-yes, I know what time it is
-meow meow
-patience, he'll be here in a moment
-meow meow meow
-yes yes, just few more minutes
-mmeeeeeeooooowwwww
-ok, he's on the stairs, wait a moment
-MMMMEEEEEOOOOOWWWWWWW (daddy's home)
and Casper takes off, doesn't even say "meow" to daddy
