Welcome!! Yes, we all do that. I'm knitting socks right now in fingering weight yarn and dropped a stitch. Or two. I had to invest in a tiny crochet hook to pick it up easily. I keep various sizes in my knitting bag.
My mother used to crochet with those tiny hooks. Not me. I got one that's really small many years ago for pulling snags back through to the other side on sweaters and such.
This is the last time I'm frogging this project for the last time.
