Is it just me or what????
I really don't think it's that big deal to say, Hey your lipstick stained my gi, would you mind taking it off before training next time?
I mean... if you are mature enough to show up and pay dues, what's the big frikkin' deal????
Yeah, I'm with Janet. If there was something I was doing that was bothering other people, I'd rather they just told me right out in a normal (pleasant) way instead of being all 'diplomatic' and 'subtle', which makes it feel like it was really a huge deal. The more casual and matter of fact, the less awkward, IMO.
