Wyjaśnienie:
dopisuję wyjaśnienie :)
jak ja się uczyłam angielskiego, to profesroka powiedziała nam taką regułę:
as soon as - jak tylko coś tam się stało
before - przed / zanim
after - po / potem / później
więc Past Perfect używasz always before BEFORE, and after AFTER :) w zdaniach gdzie jakaś czynność jest najpierw (wcześniej) a inna czynność potem (później) warto zapamiętać regułę Past Perfect
before BEFORE, and after AFTER
