I just received an SMS from my boss which says "Happy Birthday, enjoy your day! John." If it was a close friend, I would have most likely replied with "thanks John, I will :)", but since this is my boss, I am not sure in what way to reply.
Would the example above be too 'informal'? Maybe some better ideas/suggestions?
Maybe something I should mention. I don't really celebrate birthdays and never really told someone when my Birthday is. This is the first time in years someone said Happy Birthday to me and I am just not sure how to react...
