Speak, Memory--but don't say too much

I think I mentioned awhile ago that I have come up with several ideas for post here that don't involve too much work on my part. Here's another.

When I read Nabokov's Speak, Memory in the not so distant past, I came across this article from Salon Magazine, which supplements his story a little.

All families have secrets, and I suppose all writers suppress certain aspects about their family that are hard for them to admit, for whatever reasons. However, when you invoke memory deliberately, you are setting a higher bar for yourself, and editing out your younger brother in the kind of ways Nabokov apparently did involves some effort.

I admire Nabokov as a writer, though my reading of the novels is patchy at best. I did not care for Speak, Memory, though. I am wonder if this particular lapse of memory may hold some of the reasons why.
