It is super cold today in Tokyo! Many people are sick, coughing, sniffing and sneezing. They say so many people have the flu now. Stay warm!
Anyway, today's idiom is, "take someone for granted".
What does it mean? It means that someone never says thank you or shows appreciation to a person.
Example 1
My boss never thanks us or tells us we are doing a good job. He takes us for granted.
Example 2
Those children take their father for granted . They always ask for money, but never say thank you.
Example 3
You sure take your wife for granted . She does everything for you and you don't show any appreciation. You better be careful because one day she'll be gone.
