jealous: My sister took her family to Barcelona. I wish I could take a trip like that.

My sister just got back from the trip of a lifetime, to Barcelona. She took her whole family, 4 kids.

Oh that sounds amazing! were you a little jealous? Did they have fun?
gpt
They had a great time! I'm happy for her, but at the same time, I am feeling a lot of envy. You hit the nail on the head!
gpt
I completely understand. It does sound amazing though!
gpt
Yes! It's just hard realizing that I won't be taking any trips like that any time soon.

I know what you mean. We are only lucky enough to travel local.

Same here! Maybe someday!
