Your wedding might be months away but something to file away in the back of your mind is, "be forgiving". There is something strange about weddings and wedding planning that can bring out the crazy in people. They don't know they are being crazy but the emotion or the stress or the fear of the unknown can make perfectly normal people act out in a hurtful way.
When that's happens (and it will!) please remember, "be forgiving". That individual is not intentionally trying to be difficult or to offend. To you they are being controlling and unreasonable or just plain rude but they don't see it that way. If you can't forgive and let it go it can put a blemish on your perfect day. I've seen it happen way too often and it's very sad.
I wish I knew why wedding planning made some people go so kooky. It might be that everyone is trying so hard to make sure the day is absolutely perfect that they lose sight of what's really important. Sometimes trying to make sure everything looks right takes priority over another person's feelings. Some people also come in to a wedding with certain expectations or demands and when they are not met they take it personally and they do or say something they will later regret.
Don't let anyone bully you in to planning a wedding that you are not completely in love with. It is your day and you need to be thrilled with everything that happens but please be sensitive to other people's feelings and remember that once the wedding is over the craziness will go away and everyone will go back to the loving relatives or friends that you deeply appreciate. Be forgiving.
