Why do guys like to look through a girls purse?

Has happened a few times in the past where a guy mate will sneakily look through your purse and then let you in on their mischievous behaviour by randomly handing back something they took out of your purse later in the night in order to see your reaction.. is this normal behaviour from males? I thought they hated going through female handbags..
