What's a gerund? It's the thing all grammarians love and would like to see used more often. It's "ING," simply stated. Like we'd love to have people talk about the closing of a business as opposed to the "closure" of a business. Let us know when you have an "openure", okay? If you miss the gerund the way we do, then let others know with this t-shirt. It's made from 100% cotton, except for the heather shades which contain 10% polyester. It's pre-shrunk, so you can show your appreciation for the gerund for a long time. At least until all those non-grammarians out there kill it off once and for all.
