You have done great so far. YOU MOVED.
Don't rock the boat. Come late, leave early, come infrequently if at all. smile, say polite but nebulous things..."Thanks' for worrying about me" "Sure sounds good...let me check my schedule and get back to you...." "Sorry but I have to work that day, or "I think I am out of town that day"...etc. Polite...but unavailable.
If you are not creating problems 90% of elders are to busy to even think about you.
Use your answering machine and caller ID....NEVER answer the phone from elders in a timely manner. Never answer the door. Simply learn what the public has done for years....home but hiding, turn on the shower, flush the toilet.... If they really pin you down, be busy at the suggested time and offer an alternate time that is inconvenient, 8 am, 9 pm, etc. :)
