1. I’m a vegetarian. Often I'm able to avoid saying this, and because I still have a bacon and sushi loophole I'm not a true vegetarian, but sometimes this phrase will pop out of my mouth before I have a chance to stop myself. I'm not judging you and I don't care what you eat, promise!
2. I brought my own bag. I carry a cloth bag in my purse so that I can avoid taking home plastic bags at all costs, but constantly having to explain to checkers that I brought my own bag never fails to make me feel like a jerk. I usually try to play it off with a joke about saving the environment, which sometimes just makes it worse.
3. My husband and I... This is a new one, but sometimes I catch myself using the collective "we" here and there. As in "My husband and I love that restaurant" or "My husband and I are running a marathon." Which brings me to...
4. I'm training for/running a marathon. I do not want to be one of those people who only talks about running, and I feel like a total douche telling someone that I'm running a marathon. The responses vary, but they're often along the lines of Wow that's crazy/I never run at all/That sounds really hard/You must be in really good shape! I don't have a good answer for any of these, so I usually just laugh it off and change the subject. The saving grace here is that sometimes the person I'm talking to is also a runner, and then we can geek out together over running stuff and I feel like I've found a kindred spirit.
5. I don’t have any debt. This one doesn't come up as often, but when it does it's usually in the context of other people talking about their various debts (most often student loans), and it makes me kind of uncomfortable to explain that I don't have any debt. This might sound weird, since personal finance is a passion of mine and something I can talk about for hours, but I realized long ago that finance is very personal, and that people don't like unsolicited advice. I also know that although I worked like a maniac to pay off my student loans, this singular pursuit of a goal is not for everyone, and that's totally ok.
So now it's your turn: what makes you irrationally feel like a jerk? Or am I just nuts for worrying about this kind of thing?
