...'cause ppl are really prejudiced against bigger age gaps, that's why. Furthermore, most readers are in their early twenties (say statistics)...
@may,
It's true! It's true! i'm 18 and dating my 27 year old manager, that didn't go down to well at first! D:
Now we both work at different places so it's fine! :'D
it might be because in Japan professors can be very young. I work with kids from different schools and got to meet and work with lot of professors and many were near 25 years old and look even younger (Japanese ADN) XD
don't you guys ever wonder why their age difference is so little? the teachers are always in their early 20's.
