Sorry I fail at communicating.
    Sometimes I get nervous when I talk; my words don't always come out right.
Sorry about the thing I said.
     I promise it didn't sound that way in my head; I'm trying to get better at that, I promise.
Sorry I'm bad at having conversations.
     I care a lot about what you think of me. Sometimes I get scared that I'll say something wrong, so I won't say anything at all. This is one of those times.
Sorry I don't speak a lot.
      I'm really interested in what you're talking about, I just can't think of things to say right now.
  Some toddlers can hold conversations better than I can.
  Thanks for putting up with me anyway.
