Christmas came early this year
When something good but surprising happens
Lit up like a Christmas tree
To truthfully show you are really happy
Snowed in
unable to leave because there’s too much snow
Pack light
to travel with a small amount of luggage
Ring in the new year
to celebrate the end of the previous year and the beginning of the new one
Quit cold turkey
quit a bad habit all at once
To trim the tree
decorate a Christmas tree
Skating on thin ice
you are in a dangerous situation
OR
someone is ready to lose their patience with you
Don't be a Scrooge
don't be a grumpy and unkind person who doesn’t like celebrating the holidays
Santa’s little helper
someone who helps make the holidays special (kind of acting like an elf)
The proof is in the pudding
You only know if something is good by trying it.
Deck the halls
to decorate the inside of your home for the holidays
Giving someone the cold shoulder
ignore them
A Christmas miracle
Something highly unlikely but wonderful.
Off the beaten path
quiet and isolated, not visited by many tourist groups
To go on a wild goose chase
To complete a hopeless task.
The more the merrier
The more people in attendance, the better it will be.
Put that on ice
to delay or stop following something until more information is known or the situation gets better or changes
Christmas comes but once a year
It's ok to have or give a little extra (used especially for food and gifts)
Go Dutch
pay for your own part (especially at a restaurant)
Don’t look a gift horse in the mouth
To be ungrateful.
Be there with bells on
To be excited and enthusiastic
Don’t be left out in the cold
don't be left out or forgotten
Bah, humbug!
feel grumpy about Christmas or the holidays
Good things come in small packages
Don't judge something by how big it is.
