A fat grey squirrel was chasing a more slim one from the roof of our house this morning.
There was a tree nearby.
The skinnier squirrel made a dash for the tips of the branch on that tree and grabbed just the very end of the tip but held onto it. It struggled but crawled quickly towards the tree as the branch bent down and went back up the air.
The big fat squirrel dashed just a second after that one but couldn't reach the branch tip. It fell deep onto the grass below and sat there quite a while, just looking around.
Served it right!
