My girlfriend said how to send expression packs after work.

If you want to send an expression pack to respond to your girlfriend's leaving work, it is a good way to express your concern and make her feel happy. Here are some possible emoticon pack choices:

1. Smiling face or naughty expression packs: These expression packs can express your joy and happiness, and also express your welcome to her after work.

2. Shake hands or victory expression packs: These expression packs can express your support and encouragement, and also show that you are happy for her achievements in completing the work.

3. Heart or love your expression packs: These expression packs can express your love and care, and also show that you are looking forward to being with her after work.

No matter which expression you choose, it is important to let her feel concerned and paid attention to, and let her know that you are by her side.
