When an elevator door opens, make sure that u look through every faces before entering because someone u knew might be in that elevator. If u didn't notice, u will just enter and the person that u knew might just stand right behind u. He/she might think that u do that on purpose and u're such a cocky person, where the fact is, u just didn't notice because u didn't look through people's faces before entering..!
So, u know what to do???
