Re: TDKR SPOILERS (read at your own risk) - Part 5
I look at it this way...Bruce was being a bit emo to fake his death and not even tell Alfred the truth. But they had a very bitter goodbye and things were not left on a good note between them. It's one of those deals where it might have been awkward to pick up the phone. If you've ever went a long time without speaking to a parent or someone very close to you after a fight, this rings very, very true.
But in the end, time heals all wounds and when Bruce finally is able to forgive Alfred, he does so in spectacular fashion. That was probably the single happiest moment of Alfred's life.
