Expert writing Tips
Best practice
Use "shall be happy" in formal contexts or when aiming for a slightly archaic or literary tone. In most modern writing, "will be happy" is more common and generally preferred. It's better to use "shall" when you want to add more emphasis on the promise.
Common error
Avoid overusing "shall" in contemporary writing, as it can sound stilted or unnatural. Reserve it for formal situations or when consciously evoking a traditional style. It's more likely you'll want to use "will" instead.
