Not really a accident

I knew I had to pee when I left work but I still walked right past the bathroom and to my van. I wanted to stop and get a few things at the store so I did. I was wiggling while I shopped. I got all I needed and went to check out and that was when I felt my pull up get warm. I couldn't have held it any longer. This raises a question in me though. Was it really a accident? I knew I had to go and had a bathroom available but waited until I went in my pants.
