Just received the below email from MIL. Suggestions on how to respond?

Hi Red,
Been thinking about how you are going. H said he thought you had been feeling lonely. Just wanted to let you know we are here for you if you want to talk or catch up. Maybe a Bay Walk or coffee whenever you are ready? I am going to start a walking group around 'Sydney" once a month. Let me know if you would like to be part of it.
I will be away for a week from Friday as will BIL. I am off to Victoria while BIL is going to NZ skiing. Look forward to catching up soon, just let me know.
Love MIL and FIL
