Hi Martha,
I'm glad you're enjoying your time of (as my Dad used to say) peace, quiet and, tranquility. It surely must be a refreshing change.
Hope your energy and batteries are recharged so you can deeply enjoy the remaining time alone, your birthday, and your upcoming trip!
I hope, too, that your mother isn't a bigger handful when she returns home. Don't close the door to leaving May 1 or at least your brother taking over then even if you stay until mid-June. Just keep it in mind and we'll hope it's not needed.
Happy St Patrick's day!! Barbara

(green, you know!)
