Well, look at Harry's grief for Sirius. He's more or less over it by the end of summer. Under 3 months. In fact, we don't even hear much about it once Albus comes to get him after after 2 weeks at #4. Not once he's at the Weasley's - unless I'm remembering it wrong. Of course Harry doesn't actually know Sirius very well, but we only hear about his grief when he is reminded by the presence of Remus, Tonks barely corporal patronus or Snape showing up.
