You’re probably half-joking but that’s a good example of vagueness. Like, there are multiple ways to interpret this:

• “dunno”, “I’m at a loss here”
• “you’re like an old man screaming at the sky”, or “who cares lol lmao”
• “that’s just, like, your opinion”
• [insert 9001 other possibilities]

And even given the context, the reader (in this case, me) has no way to tell which one is the right one.
