Time to be honest
I have this allergy. The doctor has told me it is "balsaitis" (Balsa Itis.) He says that I am allergic to the odor and dust that is present in recently unwrapped planes. The only thing I can do is get it built and covered fast so I don't suffer from the symptoms. So if I really call in sick am I not really sick? And by building all day I am on my road to recovery.
Yeah, that's it, yeah, I can use that reason.
