I don't think that she was being hostile at you, since I was responding to your remark about only MEs taking Machine Dynamics. I wasn't trying to be hostile toward you, either, just pointing out the similarities between engineering fields, and I wasn't trying to direct my grumbling at you. We engineers should be aware that our lives suck epically, and that everyone else should be aware and need to stop complaining about their lives.
Out of curiosity, 180 credits is a hell of a lot. How many semesters did you take?
4 technical classes is still commendable. I have sympathy for all of my fellows in the technical fields.
