Are you busy Mum?

What do you say to that?
No2 son needed 'volunteers' to stuff envelopes for a mail shot of 6000 letters to go out tomorrow connected with his job.
My share of 500 envelopes took several cups of tea to complete. At least the envelopes are all self sticking!
I think I am also being 'volunteered' to stick labels on said envelopes tomorrow.
