Minulle oli aivan selvää, ettei olisi kannattanut rakastua. Järki sanoi, että niin pian kuin tunsin ihastumista, minun olisi pitänyt lopettaa alkuunsa. Tai juosta karkuun. Sanoa jotakin niin töykeää, että kaikki olisi kuivahtanut kokoon. Mutta niin ei vain tapahtunut. Kun lähelle, ulottuville, tuli nainen, joka osoitti vähänkin kiinnostusta, hän alkoi vetää minua vastustamattomasti puoleensa. Halusin viettää hänen kanssaan kaiken ajan, ja jos olin hänestä erossa, levottomuus hämmensi minua koko ajan ja minun oli vaikea keskittyä arkeen ja rutiineihin.
To me, it was quite clear that it wouldn't be worth falling in love. The logic said that as soon as I had an infatuation, I should've stopped it before it began. Or run away. Say something so rude that everybody would dry up. But such a thing didn't just happen. When a woman who expressed even a bit of interest came close, within reach, she started to attract me irresistibly. I wanted to spend all the time with her, and if I was away from her, anxiety disturbed me all the time, and it was hard for me to focus on everyday life and routine.
