Dear Nikola,

a) Thank you for your letter.
b) Thank you for your willingness to help me put my house in order.
c) Please feel free to come at any time on one hour's telephone notice.
d) Please be very careful to to do anything that might injured you.
e) Please be mindful that the house is unheated. This evening the ambient temperature is 40 degrees F. You might find such low temperatures too uncomfortable to work.
f) Please remember that you are committed to nothing, that you can stop temporarily or permanently at any time, without prejudice to your resuming later if you wished.
g) I look forward to working with you if you come. You owe me no apologies if you change your mind.
h) Our e-mail exchanges, or telephone conversations, our masked and socially distanced face-to-face conversations should be deemed independent of your helping or not helping me.
i) Thank you again.
EJM
