A relationship will be strengthen by mutual love and appreciation.
Sometimes a rose is just a rose. That is, sometimes things are just as they are; no hidden meanings, no other interpretations. If you've allowed your imagination to run away with you and have been overthinking, it's time to pull back on the reigns and slow that bolting horse down to a slow trot. Look at the evidence again, look at the actions of others and re-evaluate. Maybe, this time, it's just a rose and nothing more.
If you don't feel like talking, ask questions. People love to talk about themselves.
