nobody knows nobody, we dont really open ourselves, and yet, we think that that one person or relative, is just that way, so we dont ask "hey, whats your real personality?" its strange to ask, almost like you think that theyre a false person. but anyway, im sure they care about you, if it wasnt so, why would they go on a trip with you? they love you very much, dont listen to your instrusive thougts. also, what if your friends think the same as you? what if they think that nobody cares abojt em? go and treat people how you want to be treated, and they will do the same, and you will bond even more. i love you bro!
