Long Day

I'm not even going to go into detail about my day because, well...it would take too long. But, I do have a question.
I wonder if I can pray and ask God for something, but put a clause into the prayer? You know, praying for something, but asking that it not be too hard or take too long. I did pray for patience once. That was a mistake, because it was definitely given to me and it's not an easy one to learn. I also prayed for a stronger faith. That one was an incredible learning experience as I was sick for over a year and continue to struggle with headaches. So, at the moment, I know I should pray to love a co-worker, but I would like to put a clause into the prayer because I am slightly apprehensive about the results of loving a co-worker.
On that note, remember to pray for what you what, but know that the learning curve is steep.
