You can do this Gardner. The bill....you are right, it will just look like more mystery. You don't have to worry about it. She'll wonder and she'll ask or she won't. You don't have to tell her exactly what it was, you can be truthful and say it was phone call related to doing something to help improve you and yourself for yourself. And that's very very true.
Hold tight, listen to your coach.
You are rocking this out!
