Mr. Red Ant, me and a stranger

This happened few days ago, that morning i took a bus to college. while i was look around sitting in the bus, i saw a red ant crawling on a guy's shoelace. Its about 1 centimeter long. woohoo, i was like "its gonna be very syok if i got bite by this ant". i really wanna tell that guy about this red ant but i am just to shy coz we dont know each other xD So i keep staring at that any. A minute later that ant crawled into that guy's shoe! oh mama! i think i saw he was wearing socks so i tot that ant could bite him, but what if it crawls higher? wo..... just imagining that makes me geli. i just keep praying that ant din bite 'em. a minute later, again, that red ant crawled out of the shoe and back to the shoelace. that guys (forgot to mention that he was taking a nap) haven't scream yet, so i guess that ant din bite 'em. but i really cant stand it. putting my bag aside, i quickly wake him up and tell him about that red ant. He quickly removed the ant (i din look how he do it). when i returned to my seat, i saw that guy brushing his leg with his palm (i think he still feel the geliness although he removed the ant). he turned his head to me(i noticed that) but i was looking outside of the bus. i think he's wanna to say thanks? he turned away quickly since i wasn't looking at him. Anyway, this occurrence ended with no "casualties" and i kinda save that person from getting bitten by the ant. that day, i feel like i have done a good thing.
