She looked it up, indeed she was allowed to pat it gently. To Sarah embedding her fingerprints was half the fun, yet at least she could enjoy the other half it - the patting part. Pat, pat, pat.. in order to excersice some creativity Sarah patted her hand at different angles. It was like the picturs they used ot make with their handprint in muggle school.
