Anyway, we should probably never fight this battle of trying to convince someone what is a good photograph. If you like it then hang it on your wall!

Incidentally I have some old digisnaps of wisteria that hang in a place of high honour at my parents' place. Those shots drive me nuts, they date from before I got [back] into film. But the parents love 'em, much more so than other shots I gave them which were much more successful. You can't argue, just go with it!
