have their share of friends是什么意思?

题目

have their share of friends是什么意思?
原句挺长的：They both had their share of friends-kids（山羊肉,还是小孩?） they could hang with（装饰?）at their lockers（柜子?） or the lunchroom-but the exchanges（交易?）were mostly teenage business-as-usual.
后面附加括号的那些词影响了我对这句话的理解.
冷雨夜夜0123，但您理解错了吧，原句是这样的：
They both had their share of friends——kids they could hang with at their lockers or the lunchroom——but the exchanges were mostly teenage business-as-usual.
也就是说破折号夹着的部分是完整的句子。

答案

他们有共同的儿时伙伴,共用衣柜、厨房
但他们的交换（这个词不好翻译哦,交流或者说互惠互利）不过都是小孩子的行为
晕,原来是2个大破折号,害我前面还去找hyphen来猜
不过句子的大体意思不变
hang with是参考hang out with,闲聊的意思
他们有共同的朋友——无非是那些与他们在衣柜、餐厅闲聊的孩子（主角估计也是个孩子或学生）——不过那都是些青少年们之间的常见行为
其实很好理解,但就是不太好翻译
