If they ask about arrest then the answer is yes,if convictions then put no and don't feel guilty about it.You should found out for sure if you were arrested as a juvi or adult. You may of been charged as an adult but they still called your parents b.c your were under 18. If you were arrested as a juvi then the arrest should be sealed or expunged after a certain amt of time.
If this was an adult arrest it might show up,the fact it was dismissed and not pending would help.
