this is a great post! my opinion guys are more guilty of about 80% of what you listed. LOL
but all in all, us single peeps need to remember everyone IS human and we all have emotions so we dont need to play with anyones. also, some need to remember being nice and friendly does not = flirting. it also does not mean the person is interested in you. LOL
Thanks.
A person needs to be sure of themself before dating. I think that would prevent the above things from happening.
