I would really like to be able to do this more often. Yesterday, while doing my weekly food shopping, I remembered that this was my challenge for the day and I managged to converse for a while with one stranger.
What this task has done for me is make me realise that I'm not 'out there' often enough. So today I went out of my way to be in busier places. Did not find any strangers to talk to, but will definately make the effort from now on.
