I sound like an idiot

but I know some cars have a specific way to start it up and sometimes my yaris (2008 sedan) will do nothing on start up no grind no nothing like I maybe did the wrong thing first.
I mean you know how some cars have to be in park, I have a five speed manual by the way.
It always starts fine.... then but the pause freaks me out cause when I retry its just nothing.
Its done this from day one, never got around to calling the dealer.
Its me I know it is I just dont know why...cant find anything in the book.
It hasnt happen a lot but when it does it scares me. Im always in first gear, clutch engaged brake on prob'?
By the way Im not an idiot, usually Im really quite good w/ mechanical things (not a mechanic tho) and pc's and such but ??? I did a search on this board then again maybe I am a dim wit maybe I didnt search right either LOL!?
My husband has never noticed it doing this to him so it has to be something Im not doing or doing.
Thanks for any pointers
