['I loaned a friend a good amount of money that I knew he would pay back right away.']
Did you get the money back quickly?
I had a good amount of money saved up and I was  planning on buying a vacation trip in the next month.  A friend of mine asked if he could borrow a large sum of money from me and then pay me back shortly after.  I felt okay with loaning this money to him because I knew he would pay it back immediately
