Memories of frozen autofocus

Canon EOS 5, EF 24-85/ 3,5-4,5 Fuji Superia 200
-----------------------------------------------------------
This part of the old city is usually full of people and you can buy many traditional elements from Azeri life. But one day when it was snowly i found souvenirs outside in unusual situation. When everething was outside with a snow above them...
I wished to make picture of this space but foscusing mechanism of my camera start to make some silly moves and cold not decide where to focusing. In the same while i have been thinking about what to do on the white background i saw the cat crossing the street. All my wishes passed away and camera ignored my hunting view. Autofocus just froze and rejected to see all elements in depth of view. I just pushed assumed that it will be something soft..And it happend - :)
ps. If you know how to avoid such kind of situation speak to me please..:)
