Whatever you do don't embark on a relationship with someone thinking, 'I can't cope with this bit of their personality, but that's OK - I'll change it; you won't, you know. You'll just make both of you miserable.
I know no one who is exactly perfect - everyone can be irritating from time to time in a relationship (including you) - but you're looking for someone whose irritating habit are worth putting up with, not for someone who you can mould to your personal recquirements.
And be warned that this also applies to the big stuff that could make you very unhappy. If you meet someone who is perfect apart from being alcoholic, or physically abusive, or serially unfaithful, you won't change that either. Please don't kid yourself. They might keep the behaviour in check for the first three months or years, but sooner or later, when the euphoria (A feeling of great happiness or well-being) wears off and the stress of normal life returns, they will go back to their old ways. Don't say I didn't warn you.
