...I didn't feel obligated.

I felt thankful and thought it would be nice to let you know that.

Edit: also you seemed to show some empathy and took the time to comment that illness is also plaguing your area, so it seemed like you were an emphatic person to some degree. Thought you might be receptive and appreciate knowing.

Was a little thing, just a few words, and ,selfishly, if a few words hello you have a better day, even for just a literal moment, that makes me feel good so it really isn't a bother to state my honest feelings.

Not a big deal but im happy to have an honest interaction even if it is to someone I'll likely never see or come across again.

Cheers
