I have questions related to workplace. I have a colleague "A" who is my senior. I respect the person see them as friend. But nowadays I see A is getting distant and mad on small things. I am growing fast, I have a feeling they get jealous of me. Being senior A acts bossy even if they are wrong. Nowadays A does what they feel instead of co-ordinating with me. I still try to work harmoniously. Honestly I don't like how A behaves. I asked A what's wrong they said nothing. A is not direct with me. That behaviour is annoying, A behaves normal sometimes and non co operative/ rude at times. I value A's friend. But don't want to be a person who doesn't hold his own especially if other one becomes rude. how do I approach A? I approach them positively expecting things to be good but it hasn't helped much. Also any advice how I don't be annoyed by it.
