The most embarrassing thing ever happened to me today, and I can't get over it.
What exactly happened to you that ended up being so embarrassing?
Oh dear, I'm too shy to tell you.
I know embarrassing memories are tough to deal with, but you should try not to focus on the past too much. What's done is done and thinking about it won't make any difference. Being too worried about the past will make you miss out on opportunities in the future.
I know my friend. It happened today, so I'm still thinking about it.
Well try to use what happened in a positive way. Mistakes can be great if you are able to take a learning lesson from them. That is what mistakes are, free learning lessons!
