exasperation

I lost my work keys today- the keys I use in the course of my job.  To be a little more accurate,  I thought I lost them.  I became exasperated and  spent hours searching, rang  ‘the boss’ and he came to the rescue with spare keys –  at quite an inconvenience for him and me.  Later in the day I realized that I left them in my room in a very obvious place.  Why I didn’t  think to look there is beyond me. I would be embarrassed if anybody found out.  It seems that because they were not in my pocket that they  ‘were lost’.
