Do you think teenager makes a cridible speaker on resolving conflict,

This depends on the conflict. While a simpler conflict maybe easier to be solved by a teenager, and harder conflict might be proven difficult since they do not have the same experience as an adult may have. It also depends on the teenager, and how they approach the conflict, everyone will solve problems differently.

Hope this helps.  

Explanation:

showing or suffering from nervousness, fear, or a lack of confidence

the answer is subjective. i personally agree with the first answer for this question.

if one isn't strictly talking about objects then the correct answer would be 'my eyes' since according to this riddle i am asleep and in order to answer/open the door i need to open my eyes first of all.

however, if one is specifically looking for an object, then the first thing i would open would be the door

hope this !
