<human>: Me and my little brother were walking through Wal-Mart, when an autistic guy who looked to be in his 30's, came up and held his hand out towards my little brother as if he wanted to shake hands. 

My little brother politely sticks his hand out. Then, the guy starts SNIFFING AND SUCKING ON MY LITTLE BROTHER'S hand. (We'll refer to my little brother as derp from now on in this little story)

The look on Derp's face is hard to describe. It was a mixture "wtf, oh my God, is this seriously happening?"

Derp pulls his hand away as fast as he can. The autistic guy looks at Derp with a confused look, and then bursts out crying. 

People in the store then started looking at us with dirty looks, assuming we did something to the autistic guy. (Don't blame them)

Me and derp put down the sodas we were going to buy and walked out of the store as quick as possible while the autistic guy has practically cried an inch of tears on the floor, and receiving death stares from random people. 

When we got in the car, we burst out laughing. 

So, what's your story, Reddit?

Give me a shortened version of the text
<bot>: Guy sucks on my little brothers hand, and then starts crying when little brother pulls back in surprise. People give us the dirties of dirty looks.
