I would not say it's hate or jealousy. It's a compliment. No need to feel offended by it. Unless you're that sensitive. That person who is saying it just admires you work. Probably wishing they had the know how and done it first. But it isn't that crucial to them if they knew how to do it or not. They just are amazed by your skill.

I hate you, I hate you, I don't even know you and I hate you too, I hate all of you.
