Going to a summer fair this weekend and think this could be the ideal time to observe couples! Can I just confirm I'm trying to observe about 10 couples, and noting whether the man touches the woman and where, or whether the woman touches the man and where. Is this correct?
Do I just take the first 10 couples I see, e.g. what if the first 10 couples I see don't touch at all or do I just log the first 10 couples I see actually touching?
Is 10 couples enough?
How long do you watch them for - not sure if I can 'stalk' them for too long!

Hope this makes sense, but when I'm sitting 'watching' I want to get it right!
Many thanks.
