What do you have trouble with?

Taking a break. Weeding in the back yard. GF was over but she can't tell the difference between preacher's lice and fireweed. She one time dug up my poppy plants so I just let her take the dog home. I can't tell the difference between chartreuse and green, a major fifth and a minor seventh chord, or a finch and a nut cracker so I guess we're even.
