Great Regulars: The speaker addresses her beloved in absentia,

whom she had seen earlier in the day. She remarks that she is shedding tears as she appears to be looking at his picture or perhaps just visualizing him as in a dream.

She ponders the cause of her tears: "How/Refer the cause?" She asks him if she is the cause of her sadness or "is it thou?"
