Why so sensitive, man?

At Hebrew U, every time you enter the dorm areas, where I live, or enter the main campus, which is a twenty-minute walk up the street, you show your student card and open your backpack/shoulder bag/purse for inspection. On campus, you also go through metal detectors.

Tonight I went up to the gate of my dorms, where there was the normal two guards, one to do the inspections, and another to, well, stand there. I never understand why the second guy or girl doesn't help, but they never do. I was talking to my Dad while trying to get out my student card and open my bag, finally did so, and the guy asked me "Yesh lach nesheq?" (Do you have a weapon?) something they sometimes do, similar to the questions about who packed your bags they ask at the airports. The guy's looking in my bag already, so it's just a formality, you just say no. Once I got past him, I told my Dad that he had asked me if I had weapons, since he didn't know what I was doing at the gate.

One of my roommates, Marina, had been right behind me, although I didn't know it, and she told me when we got to our apartment that the guy overheard me saying that and thought I was complaining. She says he got all annoyed and starting asking her why I was whining about him doing his job, that we should be grateful, etc. She calmed him down, but jeez. Sure, he doesn't speak perfect English, but if he knew what I was saying then it seems like he should've been able to tell from my tone that I wasn't mad about being asked if I had a weapon with me. It's not like I told my Dad "Man, I can't believe he asked me if I had a weapon!" or acted huffy. No offense meant, guard man, I swear.

Now I feel like going down there and apologizing. I really don't know why he took it that way.
