Prompt:
### Instruction:
Improve the test suite below. Add more test methods to cover missing cases.
Only output Python code, no explanation.

### Suggestions:
# - test that is_bored('The sky is blue. I love this weather.') returns 1
# - test that is_bored('I am bored! I am very bored.') returns 2
# - test that is_bored('') returns 0

### Function:
def is_bored(S):
    """
    You'll be given a string of words, and your task is to count the number
    of boredoms. A boredom is a sentence that starts with the word "I".
    Sentences are delimited by '.', '?' or '!'.

    For example:
    >>> is_bored("Hello world")
    0
    >>> is_bored("The sky is blue. The sun is shining. I love this weather")
    1
