Dear Ms Lily,
I, Peter Terence, am writing this letter to convey you hearty congratulations on the occasion of the opening of your boutique. In the talks we have had, you have never failed to mention that you always wanted to have a boutique of your own. And today, your hard work has resulted in the realisation of your wish. I am very happy for the coming up of your dream boutique.
So, once you have started this, you would be a very busy person and might never cross the path with people like us, right? But I know that you are a very down to earth person and there won’t a hint of any such thing happening in the future. But, whatever goes around, a treat is due from your side and I am eagerly waiting for it. However, first get settled in your boutique business and then get on to the social front.
