Do you believe in karma?

When i was in need of your help, you can smile gloatingly and just walk away. But now you appear so interested, so eager.... How do you think i can embrace you with open arms? I will let bygones be bygones but it will always be at the back of my head. Now is pay back time, my subconcious mind starts to kick in. I don't have a good feeling about this. Sigh.
