Answer: I do not know if this is a multiple choice question or not, but I would contend that, on the one hand, these lines suggest that in the past he was very excited to see his friend, and, on the other hand, that he is now suffering and grieving since he is no longer there.
Explanation: Just to elaborate a little on the answer, it can be added that in this excerpt from the extensive poem In Memoriam, A. H. H. by British poet Alfred, Lord Tennyson (1809-1892), the speaker is recalling a time in the past where, in the same space where he is now, his heart would beat quickly, since he was about to see his beloved friend and clasp his hand. However, that hand is not there anymore, since his friend has passed away, and his absence makes the house and the street appear dark and unlovely to him now, and his heart does not beat that quickly anymore.
