Grammar note
“Dass” (with double s, not “das”) introduces a subordinate clause and, like “weil”, pushes its verb to the end: “dass du müde bist”, not “dass du bist müde”.
Common mistake
Don't confuse “dass” (the conjunction “that”) with “das” (the article/pronoun “the”/“that”, single s) — they sound identical but are spelled differently and have different jobs in the sentence.
