When the First Spirit arrived on the scene, Scrooge asked him, "Who and what are you?" The spirit replied, " I am the Ghost of Christmas Past." Scrooge asked, Long Past?" The Spirit answered, "No, Your Past." Then Scrooge told the Spirit that he had a desire to see the Spirit in his cap, and the Spirit cries out, "What!, would you so soon put out, with worldly hands, the light I give? Is it not enough that you are one of those whose passions made this cap and force me, through whole trains of years, to wear it low on my brow?" The Spirit had a huge stream of light coming from the crown of his head and this was to show Scrooge the past through this light and if it was covered the past couldn't be seen.
Scrooge, after seeing and questioning the brightly lit and oddly shaped, first spirit, came over with a strong desire to see the spirt with his own night cap on. Here is the quote:
Perhaps, Scrooge could not have told anybody why, if anybody could have asked him; but he had a special desire to see the Spirit in his cap; and begged him to be covered.
The Spirit, however, did not want to be covered by Scrooge's hat, and insisted that Scrooge was trying to put out the light of his own past.
