You turned 18 last week. So how was that? Did you have any thoughts of contacting your Dad at all? I'm guessing not, since he didn't hear from you.
Just found this picture and it brought back a memory. Remember how you and your Dad would go on bike rides at the canal together? He loved that special time with you. This picture was of one of those special times.
You're Dad gave you his time, his heart and his love. It's a shame what happened.
