Don't get me started on complaining... according to my wife, that's one thing I am good at, and I haven't even become a grumpy old man yet.
It's really annoying that after 2 hours desoldering an IC from an old Nokia phone, soldering it into a protoshield, having neat thin tiny cables pass routed and soldered the shield so it looks good, writing a small test sketch for it I find out the $@#%! thing isn't working. Don't you hate that?
