I put a sticker on my laptop and decided to remove it after missing how the laptop was supposed to look.
People like to put stickers on things to give a hint of their personality, but I find it to be somewhat old, by now. I thought about putting a sticker on my car, but I thought back to what I said, and I decided not to. I also pulled the plastic dealership plate covers off of it to give it a cleaner look.
The only thing I have a sticker on is my Nalgene water bottle, and that's to make it distinguishable from the many that we have at my job.
