I found an awesome pebble about 12 years ago and I still have it in my room. I never thought about it til the other day, but is that little pebble my pet rock? Who else has rocks that they have kept around?
there are some rocks and shells and fossils i've kept, every now and then i'll find them when i'm going through my shit and think "why did I keep this rock"
I keep rocks from everywhere I travel to but that does not mean they are my pets. I have a lovely cat that already fills the position of pet in my life.
is it a cool rock and possibly a reminder/memory holder/special item?
yes.
i have sea glass from a beach in every country/state that i visited the beach in. i also have some shells from ecuador, and a bunch of rocks from colorado.
It does all the same duties as a pet rock. It's a little piece of nature like a pet. Obviously it can't be like a real pet, but all those rocks you keep are your pet rocks.
