O jeez, this reminds me of a really bad experience/decision I made.

A couple months ago I went to Petco to buy a ball python. Now, I knew hardly anything about ball pythons at the time so please forgive me of my arrogance. One of the ball pythons they were selling in the tank was colored differently, and I thought to myself "Dang what's wrong with that snake? I don't know much about ball pythons so I'm just gonna go with one of these normal ones." Later after purchasing my ball python, I did quick research and found out that the python was actually a pastel, and nothing was wrong with it. Talk about epic facepalm.
