To be fair in the hierarchy of things your boss is at fault for not assisting your memory! And if **** comes rolling downhill it should hit two levels before it gets to you? If head honcho gets personal about it then it sort of undermines the two levels between you and him?
If it were me I'd be just as contrite, but I'd also make sure I had a portfolio of all my successes readily to hand.
No excusing missing the call as even if sick, you could have excused yourself earlier (I'm wearing my corporate hat for that bit)
But no harm in being able to point out, if any one needs reminding, that in all other ways you are outstanding!!?
