Why would a packet travel from the client back to the client itself?

The definition of RTT, Round-Trip Time, given in my book is as follows:

"the time it takes for a small packet to travel from client to server and then back to the client."

Why would a packet travel from the client back to the client itself?

The explanation in your book is vague. It doesn't quite convey the meaning.

Round Trip Time, or RTT, is the summation of:
1) Time taken by a request packet (sent by the client) to reach the server, and
2) Time taken by an acknowledgement packet (sent by the server) to reach the client.

Hence, in layman terms, what your book says is correct that it's the time taken by a small packet to travel from client to server and then back to itself, but in actual terms, there are 2 different packets being exchanged. One as a request to the server, and the other as an acknowledgement of reception of client's request by the server
