What weed is this?

This is in Dallas, and I can tell you it is a winter annual. It looks like parsley-piert, but it's not. It also resembles a geranium, but it's not. Also, it is highly pubescent, and doesn't root at the nodes. Thanks.

Looks like common "Mallow"

Looks like "herb Robert" a geranium relative with small, pink flowers. Very weedy, if that's what it is.

Mallow has a long single taproot. Mallow is not hairy. Mallow is not a winter annual. If you can find a blossom that would be helpful.
