What is the meaning of [You must grin and bear it]

This does not necessarily mean that you should endure misfortunes or
difficulties with a broad smile, but rather that you should put up with them
philosophically.

> ‘My wife has just flown out to Canada to stay with her sister for a month.
I’m not looking forward to having the kids on my hands and trying to keep the
home going while she’s away, but I’ll have to grin and bear it.’
