How does Liesel find hapiness during the summer of 1942?

In summer 1942, Molching, a small town outside Munich, prepares for bombing raids. Hans finds extra painting work due to the need to paint windows and blinds black. Liesel goes out with him and is impressed by Hans' cleverness and talent as a painter. One afternoon, Hans accepts some champagne in lieu of payment and gives Liesel a glass. Death writes that at this time, Liesel is the happiest she will ever be.
