(14.25 Putative should)
…
A past verb in the matrix clause does not necessarily affect the form of
should in the subordinate clause, even though the subordinate clause refers to a past situation:
・I was surprised that he should feel lonely when he was in California.
But it is also possible to use a perfective form:
・I was surprised that he should have felt lonely when he was in California.
