Ca n't believe I am back for good this time . It really felt great to unpack my bag knowing that I wo n't need to pack it again tomorrow . Little Elvis The Cat , too , was happy to have me back . We cuddled the whole Sunday . Am sitting in my office and feel slightly strange . Have n't got a clue what to do because I have been away from my projects for six weeks .

Based on the preceding passage, answer the following question What may be the reason Elvis is so happy to see me ?
I have not been home for a month and a half and he missed me .
