o.k., so i worry too much

So.... my sister-in-law invites me to go shopping with her today. I accepted, thankful that she wasn't angery with me. We had a lovely time and then she picked up lunch for my kids and I and came over to visit and play outside. During this time, she initiated the conversation of our conflicting plans. She said she is not mad and she has decided to hold one party for all 3 kids at the same time in May. Everyone will be able to attend and it will cut the cost of the party drastically. God is so good. Why do I worry about conflict so much? I think that sometimes I am so afraid of being too free with my comments & opinions (surprise, surprise) and thereby hurting someone, that I do just the opposite and say nothing. Maybe that makes me appear cold and uncaring. She is such a great person and I don't want to hurt her. I am so glad that is resolved. Now, the June party VS the company picnic, hmmmmm. What if........
