a call to sub

My phone rang yesterday or rather chirped ( I have a frog ring tone) and it was the secretary at school asking me to sub. Wow, school hasn't even officially started yet but she knew she needed someone to sub in first grade next week. Sorry to say I had something planned on that day so I had to decline but mentally I am ready to get back to a routine. For the past week or so I've taken a little break from biking/walking/daily exercise. Even though the weather is beautiful sometimes for me it is more beneficial to read books and watch birds out on my patio.
