Practice makes perfect

And some knowlege in theory makes it even better.

The second day at the vocational center in Ludwigshafen - meeting with the plumbing and heating installers, not the apprentices but members of the exam committees. Usually I don't pay any attention or don't even notice, but today I felt a bit strange being the only female left and right. There wasn't even a ladies' toilet on the floor (but one floor up at the hairdressers I was successful......). 
I'm ready for the weekend. It was a long week.

The blip is one of the training walls for installations.
