Remaining Positive

I'm trying hard to just remain positive and not be upset right now. I hate cheques. I really, honestly hate cheques. I never know what's going to happen 6 months down the line when I write a cheque now. So my landlord calls today and tells me my cheque bounced...see what I mean!! But the disgruntling thing is that I know the money was in the bank. So now I have the hassle of going and finding out what is going on...Dancing with money - the dance of death!!
