hmmmmmmmmmmmm......maybe its you , i think .
you should try to look at it this way ,
the first text was sent during the day , from ur friend ......it shows that you were in this mans thoughts....which is flattering for any female , . so he went to the bother of texting you , which is nice ..
but things change so quick now a days , that maybe your friend was busy , working , multitasking , with his wife . and when he seen the missed call , once again u crossed his mind so he txted you again .
just take the positive from it ....theres enough negative crap around
