Hello friend greetings to you, hope you are doing well and good there.

For you, welcome means to feel a lot of love. You have given the best example here; When we invite someone to our home with love, we always welcome them and it's our duty to do so. You have mentioned the moment when your sister invited you to a wedding, and then she welcomed you. You say you feel really good at that time, as you always like someone welcoming you or greetings you.

I wish you very best of luck in this contest.
