I thought people murdered groundhogs on groundhog day
Why would you think people murdered groundhogs on Groundhog Day?
Groundhogs are an invasive species, they're overpopulating. I was sure people would be trying to stop the proliferation.
Groundhogs are definitely something that homeowners need to worry about since their tunneling systems might lead to significant damage to your property. However, there is no designated day just to kill groundhogs.
I feel stupid since I thought that. I've been educated.
You aren't stupid, you just didn't know. People are not expected to know everything, you can learn something new everyday.
