I am so glad to be a boring, married person as I hear all the crazy, bad, and weird "dating" experiences of younger friends thanks to the silly Tinder app. In all fairness, the app gets the job done, and I don't think it really changes much, other than potentially making a false and slightly better first impression. ;)
The front side is concealed due to wanting to surprise the recipient. ;). If I remember, I will post it once it's been received!
