Sarcasm?

Hmm... I posted on facebook at around 4.50pm:

Hearing != Listening. Saying != Meaning. Looking != Seeing. Nothing is going right today... Wonder how today will end...

And he told me this on MSN at around 5.20pm:

Perfect life all the way siow ;x

Sarcasm, or coincidence? I hope it's coincidence... Lol...
