weed with bite
I recently pulled weeds from a planter and was shocked to find one covered in tiny barbs.They were in my ring finger and thumb. It reminded me of the time I picked up a prickly pear. I couldn't see them and had no way to stop the stinging. After a while, I remembered reading a hint for removing a splinter was to cover area with Elmer's glue, let dry and peel off.
When I peeled the dry glue there was still a stinging sensation but after about an hour it was gone and I was fine.
Learned two lessons. Wear gloves and look before grabbing weeds.
