During my lunch break I had a look around the shops. I saw a nice pullover and beautiful trousers in one place and tried them on, but they didn't fit me - the pullover was too big and they didn't have the right size, and the trousers were too short.
When I got home I took off my suit and changed into jeans and a T-shirt. I felt much better then.
