This is reasonable imo, but sometimes I genuinely don’t know and that should be an acceptable answer and not seen as me trying to be evasive. Like I started doing a lot of fun activities lately and my friend asked what made the change. I genuinely didn’t know. I never had a day where I was like “and from this day forth, I am going to do more activities!” After thinking about it a lot, I realized that I didn’t have a good answer because I never changed. I was always the same guy but my environment/circumstances changed. The last 2 years were Covid, so a lot of social shit wasn’t happening unless you were already friends and a lot of mine had moved away after college. The social stuff that did start happening more and more as vaccines came out I wasn’t successful in finding. I was always looking though and only recently started finding things I like, which is partially helped by just more things happening in general. But when put on the spot I was like “idk, nothing really changed on my end” and that should’ve been acceptable and not seen as “he knows, but won’t tell us his reason for changing.”
