I'm thinking of giving concert tickets to my crush instead of my bestfriend.
What makes you want to give the tickets to your crush?
I think she will be happy and thankful and maybe like me more.
You should probably treasure your friend over your crush because your friend will always be there but your crush is fleeting. Make sure your friend's needs are still met.
What If I want to make out with her after the day?
It's natural to want to give things to and spend time with a crush. Just make sure you don't lose your friends by neglecting them every time you have a crush on someone.
