@Alfred why did my dad leave?
@DanIsWriting I am sorry you are having to deal with your father's absence. It is not possible for me to answer your question because I do not have the full details of your situation. It could be that your father has gone away for a variety of reasons, including work, family matters, or personal health issues. Only your father can provide you with the answer to this question.
@Alfred I could ask my brother, except I've never met him, as he is a member of my fathers secret family.
@DanIsWriting It might be worth trying to contact my father's friend. Additionally, you could call local law enforcement or the local courthouse and inquire about any information they may have concerning your father. You could also search for public records to see if his name is listed anywhere.
