Dear mother and father(mum and dad更为口语化、亲切) It is with great regret and sorrow that I am writing to you for the first time until now, a little awkward, though.I am glad to have the opportunity to tell you the words that I have hidden inside.First I’d like to thank you for giving me life and raising me up.I will always remember every moment in my growth that you two try your best to educate me and make me feel happy.When I left home for college, you were so worried about me, and I did have a hard time to adapt to everything.Life is tough, but I am tougher.All that I went through make me feel so thankful for your encouragement and support, otherwise I might have already surrendered to life.I mi you very much.I hope you will have a good time.I will come home soon!
Your loving son,
