What can I do ??

Yesterday chat with someone in MSN
Then my lao po mad on me about me..
She thought I care about the girl more than her
She thought I wanna court the girl
WTF !!!
I felt really upset that she will think that ...
Until now she still think that I will like other girls ??
I knew my image is like a playboy ...
I admit I like to chat with girls ...
But really does not mean that i wanna court them lo
Actually I don't have much more guys friends
Especially who have same topic with me ....
I don't mind if other people misunderstanding me
But I really feel so sad that my lao po misunderstanding me too lo
She should knew she is the only person that I like
The only person that I want to spend my whole life with
Can't she just trust me ??
I really don't know what can I do now lo
All I can do is going to school tomorrow explain to her
