I called an old friend from school and we talked a bit about university and he expressed his insecurity about his major, telling me he'll decide as he starts studying.
I couldn't help but help him out on that, telling him I have a feeling he wants X rather than Y. He even spoke more confidently when he expressed agreement with me. Along my advice I told him that eventually he'll have to see on his own.
I continued to help him and then he just said "Well, I'll see you at university", as if it may have been uncomfortable for him.
While I'm not sure about this I am a little concerned. I had some anxiety when calling him since we haven't spoken for a long time. Add the fact that I am searching for re-connections with people since I've been alone for some time.

I don't know if I was condescending but I didn't mean to. I just let out what I had to let out without holding inside, and I had my feelings and sensitivities in play, too.

Can someone help me out on this?
