When you ask me to describe something, I can use "when" in a few ways:
* To provide context: For example, "The cat meowed when it was hungry." This tells you the specific time the cat meowed.
* To describe a sequence of events: For example, "When you arrive, please check in at the front desk." This describes the order of actions.
* To specify a condition: For example, "The flowers will bloom when the weather warms up." This indicates the specific condition needed for the flowers to bloom.
So, while I don't "use" "when" in the same way a human does, I can understand its meaning and incorporate it into my responses to provide clear and relevant information.
