My old letters

On a recent visit to my mother's to help her sort through boxes in the garage, I came across a couple of folders with my old correspondence in. After leaving university, I decided I wanted to make new friends and thought again about penpals (I had a few through the youth penpal service or whatever it was called, through my school). I came across a free ads paper and in it, there was a form for writing adverts to be shown in their sister papers overseas. There was a penpal section. I found the draft of my advert: 

Female, 21, wishing to make new friends. Loves photography, nature, travel, cacti and Star Trek.

I placed the ad, with my postal address (I'm not at the same address now) in various papers - New Zealand, some in Europe, some in the US and Canada. I had forgotten how many replies I had actually received. I am not sure I wrote to everyone who had sent a letter. I know most of that correspondence was not successful. I still have most of the letters, although most of the envelopes had the paper with stamps torn off. I also back then had drafted replies, some typewritten with many typos. One draft reply said:

I like nuts. Some people say I am a weirdo, or nutcase. I prefer to be a lunatic...

I am pondering why most of the correspondence had been unsuccessful. One comment I had attached to one letter was that it was from a religious nutcase (the letter contained only religion, nothing personal about the writer, no hobbies, no weather). Other letters asked for photos of myself. I think that this may have put me off - what does a person's appearance have to do with penpalling. OK, it may be good to put a face to a name, so some letters came with photos (no, the people were fully clothed). Another reason for failed correspondence - I think I had found a new boyfriend and didn't find much time for my postal pals of either gender. I did keep one correspondence going but the amount of letters exchanged slowed down when I had a toddler (now correspondence is just a note with a Christmas card), but I don't know what made that correspondence special to last so long.
