Wild Flower.....Corydalis

Spotted this pretty yellow wild flower growing low down in the wall and identified it as corydalis, I think.......one for Miranda's wild flower challenge.
Another gorgeous day although some cloud and not quite so hot.. Sowed some cosmos seeds in pots, a little weeding, and now some more reading in the summerhouse.
Disturb again by the neighbours behaviour either side of me...the one with the never ending tumble drier in action opposite my back door, twice a day for the last two days, had a friend visiting again, outside my door and in the garden, and the new, loud woman the other side, brought a landscape gardener down the garden yesterday evening, chatting and socialising without a care, no more than 6ft from me.....
Is it me, am I being unreasonable.....I don't think so!!
Beam me up Scottie!!

Thanks for the lovely responses to yesterday's lilac :)
