Are the others talking about writing or are they talking about other things? I think you would be perfectly within your rights to ask that your library hours - especially if they were always for the writing club - be used for writing. If that doesn't work or feel appropriate, remember that the SSFFS library while a social space is, well, a library.

And rooms can be used for socializing just fine. We did fine without the Library while I was in SSFFS: we didn't HAVE the functional library and happy space you have now. (Did I just sound old geezerish? I hope not).

And if anyone gives you crap about it, simply tell me and I'll give them a few pointers. Possibly with something pointy. Heaven forbid I have to haul my arce up to Massachusetts and beat them with a copy of the DMG.
