You're okay Rae - they're just small, "minding-their-own-business" house flies that don't bother you in any way... in fact, I bought a can of Raid and haven't bothered to get it out yet - only seen 2 flies in the entire house!!
Was a mozzie in the bathroom this morning but he looked fat, and I'm not scratching, so I think he refuelled on Woz
Believe me, if the flies started crawling up my nose I'd be crawling back on a plane home!!
EEEWWWWWWW...
Having said that, it's cold and early spring so there might be more varieties that I have yet to discover :eek
