Yeh,some people do not have a clue about how certain things are done,but portray themselves as"I know it all".I have such a person in my life who even tells the name of plants wrong.Apparently he considered himself an expert in gardening.I like gardening.I dared to correct this guy once or twice.Later I found out certain plants were dead.I showed him proudly the Jacko lantern that I was growing in my backyard and told him I wanted to carve my homegrown pumpkins for decorating my front porch.Two days later I went to check on my pumpkins and found out that the branches carrying fruits on them were severed???????There is absolutely no way to communicate with this people normally.They are toxic .
