As 'Miss' my final job (for 20 years) was in the local high school. It was really convenient as I was on hand for my own children should the need arise plus I could fall out of bed and appear in the staff room within a nano second.
Now I'm retired, past pupils expect me to stop and chat. I find I recognise the majority, can recall personal (often highly confidential) information about them but not always their names. If I don't recognise them they use eye contact and smiles until I'm compelled to ask if I know them. I've often been thanked, hugged, had my cheek pecked and even been asked by two if I'll look after their children while they work which I find quite flattering. Most insist on giving me staff discount or freebies, or go the extra mile to help me in their professional capacities. If I'm introduced as 'my old teacher', I smile and gently suggest replacing 'old' with 'former'. I enjoy meeting them and catching up on their news.
Nowadays we holiday in term time as it's less expensive and quieter. Once, in Lucca, when we were paying through the nose in August and looking longingly as figs were ripening but not yet ready to eat, DH and I thought a grandmother excessively stern when she told her DGC to go to their rooms immediately if they created a scene by the pool. Years later, we appreciate her consideration and thoughtfulness!
