Okok.. Honestly? IT can really work on alot of girls. But
somehow or rather, no magical effects on me.
I'm doing this from a mobile phone now, so it might not be all that

not take us seriously! But then again, it could be because I'm just
a big buaya and it's hard to take a buaya who is buayaing you.
