I actually know the feeling. Still, the only real question you have to answer about any of the threads you're considering to drop is "Am I having fun with this RP?" If the answer is a maybe that leans towards no, or outright no, then consider "Is there anything I or my RP partner can do to make the RP fun and keep it fun for any decent length of time?" If the answer is still no, then just drop the thread. It's been my official policy to always drop RPs if they're not fun for either myself or my partner, and I think it's one that makes quite a bit of sense considering why we're here. ((Well fun and 'fun' in the perverted sense...))

In any case, I hope my nattering helped. If not, well, at least we got to exercise our typing fingers a bit more. XD
