Pink is for Girls

A shirt that Anirud's grandparents had sent him for Deepavali happened to have shades of pink colour. He immediately refused it saying that it looks girlish to wear that. On the other day, we were at a shop and were looking at a mat that was in pink. Anirud could not even digest the fact that we were looking at something that only girls would use. He doesn't specifically say that pink is for girls, but in general keeps that colour away saying that it is meant for girls. Wonder if someone told him all these or he picked it up through hearsay.
