Snuffy,
it's not a Storm poem, but the second stanza of the song "Dat du min Leevsten büst", referred to above. By the way, T. Storm wrote in High German; until now I didn't find poetry done by him in Low German.

Susanne,
no dispute about the qualities of "Dat du ...", but nevertheles it doesn't fit to Edmunds question about boy knocking at girl's and begging to be let in.
