Same thing happened to me a couple of months before my 20th
When I realised I could no longer use "I'm a teenager" as an excuse for all the stupid things I do.

I was relieved when I realised I can still (currently) use "I'm a student".

In my defence, I do not do many typical stupid teenage things.
However, I'm glad to be able to use the "I'm a student" excuse if I need to!

Mine mainly concern getting lost while drunk
And finding myself wandering the wrong way down dual carriageways (miles away from where I live/stay) at 4am.

I don't need to be drunk to get lost.
Also, I don't go walking alone out at night where I live when I'm at uni. Too many dickheads.

Ah
But if you do it in February in a thunderstorm, they stay indoors.

As for dickheads after dark, over the course of a month in Wester Hailes (Edinburgh suburb) I had a firework launched at me and nearly got thrown into the union canal three times.

I stopped cycling after dark...

Our February thunderstorms are fairly impressive.
That's a fairly sensible thing to do, not cycling after dark when dickheads are about!
