You need to be a guardian.
you never use it
No, you have to be legal guardian.
It depends on what your parent or guardian thinks.
You need to be a guardian in AdventureQuest. Then got to dragonfable homepage and go to guardian verification. Type in your Adventure Quest Username and password and then you type in user name and password for DragonFable account. Then choose character you want to be Guardian. Then the next time you log onto that character u can go to the guardian tower and get guardian armor. You can only use your Guardian account one time. If you want to get another guardian in Dragonfable you have to get another guardian account.
i do not know how to use embalming in a sentence. (there is the sentence)
So- you are asking when to use 'when' in a sentence. When you are asking how to use when in a question, you are already using when in a sentence, because a question actually is a sentence. I like to use when in a sentence whenever I like.
