Analysis:
This is an informal conversation, As it is immediate and spontaneous as this was on a social networking site so everything would have been improvised,Also this Facebook message is an interactive dialogue as this is a conversation between two people, This is also a private one to one as the audience/receiver is known.
This conversation is partially context dependent due to the fact that you need to know the subject of this message or you wouldn't understand what the conversation is about, This is also message oriented as it is a Facebook message.
If you look closely I use the word 'Yeah' which is completely different as opposed to the word 'Yes' as it is used for me to let the person know they can carry on the conversation, Also there are a wide range of personal pro nouns in this conversations for example 'I'll holla you" or "I didn't mean it" as in conversations we tend to talk about ourselves and even much more simple we speak in first person in conversations.
Although this is less formal on the scale of formality, There is a wide range of punctuation for example commas and question marks, This is due to the fact that I still find it important to use punctuation as it is easier for the receiver to understand what I'm talking about at specific points.
If you follow this conversation clearly you can see the illocution of me saying 'it was fine' is that I want you to leave me alone, I also use 'Errrrrr' as a word to fill in a gap as substitution for another word I can't quite yet come to, Which throughout you see a lot of fillers.
