wow thinking about this alone makes me laugh, thinking about my childhood I don't know what to say but I will share the experience i have when i was 13.
it happened when i was in grade 6, then i have a girlfriend who we both share the same name in class, i liked a alot that we both exchange our sitting position in class because we sit close to each other and she do wear my shoe.
it was a very funny experience and my teachers called us twins but it happened after my grade 6 when we all graduated we lost contact and we stay very far away from each other for 7years.
when I get into the university we get to meet again and i have forgotten what she looks like but at first sight she recognized me and i was surprised the name she called me because no ones knows the name, i was shock Her look changed so much but one thing i recognized was her eyes balls still beautiful as before.
it happened at that point she was married with a lovely son, i was so happy for her and was a bit disappointed for not looking for her.
