Bindweed is usually white-flowered, and the flowers are noticeably smaller than the Morning Glory vines whose seeds are sold in packets at gardening centers.
I've seen each, and I'm sure most of us have, whether or not we identified Bindweed at the time. The ornamental Morning Glory blooms are maybe 2" across from edge to edge and are (usually) variations on purple or "blue"; the bindweed I saw in Newark, California, in an industrial "office park parking lot" had blooms max. 1" from edge to edge. Every one of them was white.
Maybe this will help a little in identification.

Bad couple of days w/Vergil; he developed an infected left wrist (the vet said these things can happen spontaneously, with or w/o surgery
) Wed afternoon/Thurs morning. He's been treated for this + the knee surgery, but max. dosages of pain meds, NSAIDS + Fentanyl patch (!) aren't doing the job, and he can't get to sleep unless he's completely exhausted....
