I was wiring up my for a 2x16 LCD display project. Accidentally GPIO 2nd pin(5V) and 6th pin(ground) came to contact and Pi got rebooted.
While coming back up it took a while at one step (some Ethernet step) and finally came back up. And now everything is back to normal state.
Am I got lucky that my Pi did not get fried?

Are there any particular GPIO Pins that I should be much careful about?
Thanks,
Simon Mandy
