Frontend-Developer steps into my office and tells me that my code does not work and that he has checked everything.

>me confused, cause I did it every time so<

So I spent one hour to check and recompile my code again and again. I created more console outputs than my whole last week... And at the end... It was not my fault, I had to find out that the front- and backcolor of his label are the same so the text was not visible.

Dear frontend developer,

I love your designs and most of the time you make a really good job, but please check something like this before you confuse a backend developer for one hour and let him doubt about himself...

Thanks!

Sincerely,
Your backend dev
