It is rare to find a good friend who will be with you through good times and bad.
A trustworthy, genuine boyfriend or girlfriend can often become your best friend.
But it still beats strangers who will just leave you when things does not work out at all.
Best friends will stick with you even when you are not couples anymore albeit minus the intimacy.
Being your best friend means that both of you have known each other inside out including your strengths, weaknesses and quirks.
Despite all of these, if both of you still decided to go ahead and move up the relationship one level up it will be a much more comfortable and less awkward experience compared to girl/guy you just happened to meet and started to date.
But what if you were already best friends from the start?
