Continuing with the off topic diversion into singing...
It's actually the thing I miss most when my boyfriend goes away. The constant noise. If he isn't singing, tapping, humming or similar, its keyboarding bashing, tromboning, and now he's threatening to get a guitar...
And now three of my housemates are all in the same choir, so if I wander into the kitchen at certain times, I am guarenteed to be met by cheery three part harmonies...
*wistful*
Occasionally they even catch me off guard and I end up joining in...
Anyway, I guess the point of this ramble is that I guess amont of singing depends on your household.
