I will be gone for about a month and will be unable to use the computer.

I will see you all when I get back

Sorry to hear you will be gone. Hope all is well with you and your family.

Good, hurry back and bring a case of hot sauce when you do, okay Dem? Miss you.

See you when you get back.

If it's not a vacation, I hope you'll find some opportunities to treat it like one.

Time flies. See you soon!
