Ehh, much as it doesnt really do much harm to delete, it also doesn't do anything useful to delete it, so, I'll posit that you just... care too much? Why does it bother you to know you asked a perfectly normal question? And, as for not liking seeing them... then why do you go out of your way to go back to them?
Simply put, seems like a personal problem that would be better tackled by questioning yourself and coming to terms with things than to simply let it continue (me deleting it doesnt stop the behaviour really, it just reinforces what you have done/are doing/will do)
