He couldn't come up with a better excuse than that? Here are some suggestions:
He had just fixed a bowl of cornflakes and had to eat them before they got soggy.
He just took a shower and wasn't dry yet.
His bag of M and M's didn't have any blue ones and he had to file a complaint with Mars.
Bibi’s excuse was amazing - he said that he could not afford the trip. Really. That was the statement - from a Head of Govt.
