Make sure your frugalness isn;t coming off as cheap and annoying. It's hard to tell unless you step back and take an honest look. I had a frugal friend who was quite annoying about it. She would make a big deal about having to spend some money to come out for a dinner with us, even though we only met a few times a year at most. Then she whine about it all night makign the rest of us quilty. What she didnt; understand was that it wasn;t about paying for a meal, it was about coming together adn seeing old friends and having a good time in general. It made the rest of us feel as though our friendship wasn;t worth it. Sometimes she will do embarrassing things like sit at a restaurant and order just a water, or not paying her share of the karaoke room becuase she doens; plan to actually sing through the mic.

I'm sure you aren't doing the same things, but maybe make sure that you arenot doing anythign that might be annoying or embarrassing to someone else. Some people get annoying easily but don't say anything about it, except to make jokes.
