And if you don't "remember" A, the reflog is here for you.

$ git reflog show HEAD
$ git reset --hard HEAD@{42} # not "the 42th ancestor"
                             # but "where HEAD was 42 moves ago".

By default, the reflog will expire after IIRC, 3 months, and git-prune will not prune the objects while they are reachable.

So, it's even safer than you say ;-).
