Meadow brown and small white butterflies on thistle flower

Thistle flower. A meadow brown butterfly was feeding on the flower, then a small white butterfly came along. After some hesitation and a couple of false starts, it landed and started to feed on the opposite side of the same flower. After a short while, the white took off again and flew off, with the meadow brown continuing to feed.
