could my friend be jealous

Hi the other i was going to the bus and saw my friend and my other person came behind me and started talking to me and asked if i am in a hurry to get out of here and i said yes ,this place ,stinks ,but i used the other word for stinks ,also starts with s' and one of my friend laughed but the other one did not and my other friend ,was acting strange ,we don't talk anymore ,long story but my friend did wave to me but was walking kind of slowly to get to the bus. and when my other friend went away ,i wave to the other friend and he said i don't think he saw you but he did and i think my friend kind chunked, the one i waved to. do you think my friend hates me or is jealous that i am not taking to him?

Then the next day i saw him and i wave to him and he wave back ,kind of quick.

then at the bus i saw him he was walking slow and i was behind him and when he saw me about to pass him ,he turn and look at me and waved and someone i knew said hi to me and he was near by walking slow and i wave again ,when he got to his bus and he wave again. why do you think he was walking slow for ?
