I think it's a clear sign that it's the selfish genes talking, puppeting your higher functions to make sure they survive. Not for any reason, but just because those are the genes most likely to continue reproducing.

It's a bit egotistic, but I like to imagine I've sublimated the drive to reproduce, by helping out my friends and their kids when I can. Hehe stupid genes, you think these are your kids because the bonds of friendship getting crossed wires with direct kinship. Stupid-ass genes, you don't even know your ride ends here.

Yeah it's really egotistic, but it's a fun little fiction.
