I think it´s very hard or more or less impossible to know how this teacher would react. In some other forums teachers write about how they got a letter or a card from a former student and how happy that made them. Several also recommend me sending a card.

As this teacher is the only one with her name in this city I only had to search for her on our "White pages". Me personally hadn´t found that creepy if I knew I was very easy to find.

In some ways I think she probably has enough with the people she already has in her life and in other ways I think she might think it would be fun to talk to/send mail to a former student from so far back. She´s in her eighties.

I don´t actually risk anything as the possibility to meet with her randomly again is more or less zero. The town is rather big and I spend very little time here as I don´t live here any longer, I was just visiting some family.

If I got a greeting from someone who met me twenty years ago I think I had replied even if I didn´t remember that much of the person. At least if I understood I meant something to him/her.

There´s of course always a risk that this teacher feels she doesn´t want to start any new contacts and feels we don´t have anything in common beside that time in school back in the days.

In a way I understand it might feel intrusive and at the same time there are so many sources for finding people so it´s not that you need to pry to find out someone´s address. Perhaps the thing itself, looking someone up, is what feels intrusive to some.

It´s like either or, she might be glad and find it fun that I recognised her after all those years and don´t mind sending me some lines back. Or she´ll find it odd getting a card from someone she hasn´t met for very long.

I would be thrilled if an old teacher I liked suddenly sent me a card and looked me up to find my address. But I´m not that fussy about people looking for information like home addresses and similar.
