Cool or creepy...?

At what age does doing something solo stop being cool and turn into creepy?

By "doing something solo", I am referring to attending a very public, all ages, event. (...such as a concert, or race, or sporting event, etc.)

Is the concept of "cool" and/or "creepy" dependent on the mindset of the solo individual or the majority of the crowd that surrounds the individual?

Is doing something solo ALWAYS cool?

Is doing something solo ALWAYS creepy?

Can doing something solo have elements of both cool and creepy? Or must it be one or the other?

Solo AVAS Project is so much more than the name of this blog... this is my life.

I do (most) things solo.
