One day, I heard that I had a baby sister．I didn't think much about how to communicate with my sister that first year because she was a baby and babies don't do much talking．Later, the family found she couldn't hear anything．So my family began learning sign language．But I didn't like it, and I did my own things．My parents spent hours with my sister teaching her and themselves by playing sign language games．
Years passed．One day my mother asked me to sign something, but I failed．My mom felt very sorry．She was so sad that I didn't care enough about my sister．This hit me deeply, knowing how selfish I was．I needed to talk to my sister, but I couldn't even sign easy words like, “Where are you? ” Then my family and I started going to sign language classes at my sister's school．We sat down as a family watching sign language movies and playing sign language games．
Today I can communicate very well with my sister．It brings a smile to my face when my sister signs something to me．I have realized it was no fun not knowing what my family was saying．So if you have a family member with special needs, put this person in your mind first．
