ot: do you think someone is insecure or lying?

Definitely lying. Heck, I never volunteer my income info to anyone and when I get asked, such as when I apply for a credit card or open a bank account, I always say I make less than I actually do because I don't want people to know that I'm making so much.

The only time I gave my actual income is when I applied for a home loan because they're going to ask for my tax returns so there was no point in lying about it.
