want to relax after a difficult day
to chill out
the coldest part of winter
the dead of winter
to delay something for a little while or to stop doing something
to put it on ice
to put on warm clothes against the chill of winter
to wrap up warm
when something grow in significance or size in an increasingly faster rate
a snowball effect
to create a friendly atmosphere
to break the ice
to have a lot of work or other things to deal with
snowed under
a small part of a problem that is much bigger
the tip of the iceberg
to feel nervous or frightened about something because you think it will fail
to get cold feet
to be in a little bit of trouble or in a risky situation or position
on thin ice
