If you empathize with them, you'll prolly discover that they have attempted some things in that time and were simply wondering if you did the same. I'm sure most don't do it for the fun of pointing out but to connect and find common ground.
How you react to the question is up to you, not them.
Easier said than done! Its hard as hell but thats my view on life...people are people, can't do anything about them. All you can do is learn and possibly change yourself.
I'm doing me. I'm doing me. I'm living life and this is what Imma do till it's over..till it's over..but it's far from over.
Then ask them how their slow death march is working out for them...and thrill them with all the possibilities you still have open to you. No responsibility. No commitments...the world is literally your oyster. Figuratively speaking of course.
i'm 23 and haven't figured it out either. i was really down about it earlier this year but i keep meeting more and more and more people around our ages who are in the same place. and people older than us. and people older than us who have changed life directions multiple times.
i feel like the people who get on our backs about it are the ones who have the problem, not us. why do we have to have it all figured out now? just to suit their cookie cutter model of how life should go? no, thank you. we will dance our lives to our own rhythms.
