to protect my newlt glossed windowsills?

[ChaosTrulyReigns]

By sitting on my arse on this sofa for the foreseeablr future?

Who knows what could befall them if I leave this seat and fail to guard them?

AIBU?

You are actually going to it and watch paint dry???!!

Sit and watch, even.

YANBU - I left mine unattended, and there were footprints on them....
Gruffalo footprints

Nope.

I am going to watch TV and keep the DC and cats away.

Flies can look after themselves.

This is passive supervision.

Pass me the biscuits, please.
