September is a month of "firsts" for many school age kids, but there are some rights of passage - such as the first sleepover - that adults and kids can't agree on which age is most appropriate.

For instance, when it comes to wearing makeup, a survey conducted by The Harris poll found that Americans - on average - say a kid should be nearly 15 years old before venturing into Sephora. However, teens say they started wearing makeup at 13. The survey asked about first dates, first kisses, first jobs, and more.

What ages do you deem most appropriate?
