What does a series of dots (elipses) mean after a sentence?

For example you send an email to a acquaintance or friend. "I've been busy. Recovering from unexpected surgery. My recovery is going well. I will send information on that hobby to you soon. Hope you're day is wonderful."

Their response. No problems. Thanks for the note. Hope surgery went well.... Rest up...

What do the dots signify or mean?

Thank you for your input! :)


Solution 1:

Generally they mean some missing part of the text. Here informally they just mean a series of messages with pauses.
