The context of the following conversation is Cameron wasn't sure which one to decide, so he kept his options open.:
Cameron says I wasn't sure which dress to wear to the wedding so I bought both..
The friend responds Why would you buy two dresses that are so similar?.
Cameron responds Because I couldn't decide and was wasting so much time in the store..
The friend responds Well which one do you like most?.
Cameron responds I told you I like both of them. I will return the one I don't wear..
The friend responds Isn't that more wasted time?.
