Case 1: Last week
A good friend of mine called me up and told me that she was surprised to discover that me and Mrinal got engaged, our marriage date got fixed and we didn't even inform her.
Case 2: Last weekend
One of Mrinal's friends called him up to confirm if we are getting married on 18th November.
Case 3: Yesterday
One of my friends happened to call me up and mentioned that she wasn't aware that me and Mrinal got engaged.
Of course, they all were really happy for us and it felt so good to receive marriage related calls already, and I wish that all of the above becomes a reality soon. However, the fact is that neither our marriage date is finalised, nor we have had any engagement ceromony. Yes, as we aren't going to have any engagement ceremony at all, you may assume that we are engaged. About marriage, of course, we'll announce it as and when it is finalised.
Oh, the celebrity status and the rumours! He he he.
