I've tried talking to em, got acknowledged, but he didn't respond. Then started avoiding eye contact and choosing different paths so we wouldn't run into each other. Also If we're in the same area he leaves to a different one. Him and another coworker actively avoid me, the other one idk why. I haven't interacted with him much, but did notice the one who avoids me(coworker A), tell coworker(B) something. Now coworker B always looks away, and I feel bad for it. Cause we had very little interaction
